The Climate features of summer sandstorms show that the season is rich in the disasters for the Gansu region, concentrated mainly in the Minqin, Dingxin and Jinta areas. The synoptic analysis of a rarely observed strong event indicates that in summer such dominant weather systems as the upper-level weak trough, shear line and thermal low are responsible for the sandstorm while in spring the tempest is generally triggered by large-scale systems. The upper-level jet's behaviors are not so manifest before the occurrence of the summertime sandstorm, with the jets suddenly intensified almost concurrently with its occurrence, which is one of the difficult points for forecasting the summer sandstorm. Now for the study we make use of satellite imagery and its sensings-based tracking as a more visualized tool for monitoring the onset, movement and coverage of the disaster.

IASI was successfully launched on MetOP A on 19 October 2006. After the in-orbit commissioning, the performances of IASI were evaluated during the Cal/Val of level 1. Key parameters of instrument and on ground processing have been fixed for optimal performance and best quality data delivery. The first spectra and images of level I products show all the potential of IASI data for expected applications. Some illustrations are given here with maps of pseudo channels sensitive to trace gases, atmospheric profiles or maps of surface temperature qualitatively compared to maps from models. Level 2 processing to get these parameters has been implemented at Eumetsat and some products are currently under validation. The quality of IASI data paves the way to additional very promising products. A thorough analysis of cloud free spectra has been performed to extract the small signature of minor species like CFCs and HNO3. Nevertheless, the main limitation of IASI data remains clouds. It is showed here with the cluster analysis of AVHRR data registered in the IASI pixels and delivered as level I products that only a few cloud free pixels can used for full retrieval. A method making use of the cluster information has been developed. It permits to strongly increase the statistics where clear column profiles or columns above clouds can be retrieved. This scheme will be applied to the retrieval of the CO2 where large data set are needed to extract information from the spectra.

Three-fold restriction technique is used to determine the standard deviation of the error in the total-ozone content obtained from the three independent data resources such as ground-based station data, TOMS (Total Ozone Mapping Spectrophotometer) and GOME (The Global Ozone Monitoring Experiment) in 1995-2004. The results show that, in general, the accuracy of TOMS V8 data is the best and that of ground-based observations is the worst. Since the ground-based observations can be classified into 3 types according to the equipment principles such as Filter, Brewer and Dobson, the standard deviation of the errors for the 3 types of ground data are also calculated with the 3-fold restriction technique and it has been found that the Filter has the largest error, the Brewer is the second, and the Dobson is the least. The data quality at Shiangher Dobson Station of China is better than either TOMS or GOME. The data quality at Waliguan Brewer Station of China is better than TOMS, but worse than GOME. The error in TOMS V8 is evidently less than in TOMS V7 because of the algorithm amelioration of TOMS V8 over TOMS V7.

The application of infrared hyper-spectral sounder data to climate research requires the global analysis of multi-decadal time series of various atmosphere, surface or cloud related parameters. The data used in this analysis has to meet stringent global and scene independent absolute accuracy and stability requirements, it also has to be spatially and radiometrically unbiased, manageable in size and self-contained. Self-contained means that the data set contains not only a globally unbiased sample of the state of the Earth Climate system as seen in the infrared, it has to contain enough data to contrast clear with average (cloudy) data and to allow an independent assessment of the radiometric and spectral accuracy and stability of the data. We illustrate this with data from the atmospheric Infrared Sounder (AIRS) and Infrared atmospheric Sounder Interferometer (IASI) data. AIRS and IASI were designed with fairly similar functional requirements. AIRS was launched on the EOS Aqua spacecraft in May 2002 into a 705 km polar sun-synchronous orbit with accurately maintained 1:30 PM ascending node. Essentially un-interrupted data are available since September 2002. Since October 2006 IASI is in a 9:30 AM polar orbit at 8 15 km altitude on the MetOp2 satellite, with data available since May 2007.

The Microwave Sounding Unit (MSU) on board the National Oceanic and atmospheric Administration (NOAA) polar-orbiting satellites were designed to measure the atmospheric temperature from the surface to the lower stratosphere under all weather conditions, excluding precipitation. Although the instrumental design and calibration were made primarily for monitoring the atmospheric weather processes, the MSU observations have been extensively used for detecting climate trend. However, calibration errors have been a major uncertainty in climate trend detections.. In order for the MSU data to be of high quality for climate trend and variability research, we have recently recalibrated the MSU satellites NOAA 10, 11, 12, and 14 using simultaneous nadir overpass (SNO) method. The calibration results in a well-merged 20-year radiance dataset for the MSU channels 2, 3, and 4. Limb-correction is applied to adjust the incident angles of the footprints. The limb-corrected radiances are further binned into 2.5(0) longitude by 2.5(0) latitude grids to generate deep-layer temperature datasets for the mid-troposphere (T-2) tropopause (T-3) and lower-stratosphere (T-4). The global ocean averaged trends for the recalibrated T-2, T-3, and T-4 are respectively 0.234 +/- 0.071 K/decade, 0.079 +/- 0.085 K/decade, and -0.414 +/- 0.287 K/decade for the 20-year time period from 1987 to 2006. Both the recalibrated radiance and deep-layer temperature datasets are freely available through the NESDIS/STAR website http://***/smcd/emb/mscat/***.

The remote sensing Group at the University of Arizona has been active in the vicarious calibration of numerous sensors through the use of ground-based test sites. Recent efforts have included work to develop cross-calibration information between these sensors using the results from the reflectance-based approach. The current work extends the cross-calibration to the AVHRR series of sensors, specifically NOAA-17, and NOAA-18. The results include work done based on data collected by ground-based personnel nearly coincident with the sensor overpasses. The available number of calibrations for the AVHRR series is increased through a set of ground-based radiometers that are deployed without the need for on-site personnel and have been operating for more than three years at Railroad Valley Playa. The spectral, spatial, and temporal characteristics of the 1-km2 large-footprint site at Railroad Valley are well understood. It is therefore well suited for the radiometric calibration of AVHRR, which has a nadir-viewing footprint of 1.1 × 1.1 km. The at-sensor radiance is predicted via a radiative transfer code using atmospheric data from a fully-automated solar radiometer. The results for AVHRR show that errors are currently larger for the automated data sets, but results indicate that the AVHRR sensors studied in this work are consistent with the Aqua and Terra MODIS sensors to within the uncertainties of each sensor.

The AIRS Science Team Version 5.0 retrieval algorithm became operational at the Goddard DAAC in July 2007 generating near real-time products from analysis of AIRS/AMSU sounding data. This algorithm contains many significant theoretical advances over the AIRS Science Team Version 4.0 retrieval algorithm used previously. Three very significant developments of Version 5 are: 1) the development and implementation of an improved Radiative Transfer Algorithm (RTA) which allows for accurate treatment of non-Local Thermodynamic Equilibrium (non-LTE) effects on shortwave sounding channels;2) the development of methodology to obtain very accurate case by case product error estimates which are in turn used for quality control;and 3) development of an accurate AIRS only cloud clearing and retrieval system. These theoretical improvements taken together enabled a new methodology to be developed which further improves soundings in partially cloudy conditions, without the need for microwave observations in the cloud clearing step as has been done previously. In this methodology, longwave CO2 channel observations in the spectral region 700 cm(-1) to 750 cm(-1) are used exclusively for cloud clearing purposes, while shortwave CO, channels in the spectral region 2195 cm(-1) to 2395 cm(-1) are used for temperature sounding purposes. The new methodology for improved error estimates and their use in quality control is described briefly and results are shown indicative of their accuracy. Results are also shown of forecast impact experiments assimilating AIRS Version 5.0 retrieval products in the Goddard GEOS 5 data Assimilation System using different quality control thresholds.

To meet future earth system science challenges, NASA will develop constellations of smart satellites in sensor web configurations that provide timely on-demand data and analysis to users, and that be reconfigured based on the changing needs of science and available technology. Sensor webs can eclipse the value of disparate sensor components by reducing response time and increasing scientific value, especially when integrated with science analysis, data assimilation, prediction modeling and decision support tools. The prototype Land Information Sensor Web (LISW) is a project sponsored by NASA, trying to integrate the Land Information System (LIS) in a sensor web framework which allows for optimal 2-way information flow that enhances land surface modeling using sensor web observations, and in turn allows sensor web reconfiguration to minimize overall system uncertainty. This prototype is based on a simulated interactive sensor web, which is then used to exercise and optimize the sensor web - modeling interfaces. These synthetic experiments provide a controlled environment in which to examine the end-to-end performance of the prototype, the impact of various design sensor web design trade-offs and the eventual value of sensor webs for particular prediction or decision support. The Study of virtual Land Information. Sensor Web (LISW) is expected to provide some necessary priori knowledge for designing and deploying the next generation Global Earth Observing System of systems (GEOSS). In this paper, the progress of the LISW study will be presented, especially in scenario experiment design, sensor web framework and uncertainties in current land surface modeling.

Determination of aerosol optical depth from satellite remote sensing measurements is extremely complex due to the large variability of aerosol optical properties. Significant simplification occurs when measurements are taken over water since the ocean reflection signal can be taken as negligible in the NIR.. Unfortunately, over land, most of the signal can be attributed to ground reflectance. While conventional approaches look for "dark" pixels in an image to isolate aerosols, these pixels are subjected to increased noise. In this paper, we focus on the feasibility of the MODIS sensor to determine aerosol optical depth. In particular, an intercomparison between MODIS and CIMEL shows a significant trend for MODIS to overestimate optical depth. We show that this may be explained through an inaccurate assumption on the correlation between the VIS and NIR surface albedos. In particular, we show through an analysis of hyperspectral high resolution Hyperion data that the correlation coefficient assumption underestimates ground albedo resulting in an overestimate of the VIS optical depth. Using a series of coincident measurements between aeronet and MODIS, we estimate a more accurate angle dependant albedo and use it to determine aerosol optical depth. The results show significantly less overbias. Our efforts to reduce space resolution to 1.5km are also discussed.

ECMWF daily reanalysis is applied to investigate 1961-2001 heat source/sink and the climate features in relation to the atmospheric heat distribution over the QTP (Qinghai-Tibetan Plateau) by means of the "inverse algorithm". Results suggest that 1) in March-September (October-February), the QTP acts as a heat (cold) source, the strongest being in June (December). For the region as a whole, the heat source feature lasts longer, with its intensity much higher compared to the cold source;2) as shown in the heating vertical profile, the maximum heat source layer occurs dominantly between 500-600 hPa, but with the season-dependent heating strength and depth, and, in contrast, the cold source has its maximum layer and intensity varying as a function of time;3) the horizontal distribution of the heat sources throughout the troposphere < Q(1)> (from surface to 100 hPa) is complicated, displaying noticeable regionality, i.e., the heat source changes faster in the western than in the eastern QTP, with the western source considerably stronger in April-August, and intensified quickly enough to show a 200 W/m(2) center in May, one month ahead of the eastern source. When July comes the regional heat source begins to weaken towards the south, during which the western source weakens faster, changing to a cold source in October, again one month earlier compared to the eastern counterpart;4) since 1979 the seasonal Variability of the heat source has shown climate transition signals, as clearly seen in 1990/91.
