drought is a major environmental disaster in many parts of the world. knowledge about the timing, severity and extentof drought can aid planning and decision-making. drought indices derived from in-situ meteorological data have coarsespatial and temporal resolutions, thus, obtaining a real-time drought condition over a large area is difficult. this studyused advanced very high resolution radiom...

The Advanced Very High Resolution Radiometer (AVHRR) instrument on-board the METOP satellite is designed to provide very accurate measurements of Sea Surface Temperature (SST). In this work, using one year of METOP-AVHRR data and a geostatistical approach, we characterize the spatial anisotropy and non-stationarity of the SST variability using oriented ellipsoids. The method is also able to sep...

Thresholding based method for rainy cloud detection with NOAA/AVHRR data by means of Jacobi iteration method is proposed. Attempts of the proposed method are made through comparisons to truth data which are provided by Japanese Meteorological Agency: JMA which is derived from radar data. Although the experimental results show not so good regressive performance, new trials give some knowledge an...

Surface solar radiation (Rs) is essential to climate studies. Thanks long-term records from the Advanced Very High-Resolution Radiometers (AVHRR), recent release of International Satellite Cloud Climatology Project (ISCCP) HXG cloud products provide a promising opportunity for building Rs data with high resolutions (3 h and 10 km). In this study, we compare three satellite based on AVHRR over C...

Accurate monitoring of albedo trends over snow is essential to evaluate the consequences global cover retreat on Earth’s energy budget. Satellite observations provide best way monitor these globally, but their uncertainty increases snow. Besides, different products sometimes show diverging trends. A better assessment fitness satellite for needed. We analyze consistency black-sky estimates from ...

Front Cover: The figure illustrates the geographic distribution of the USGS land-cover categories based on the AVHRR satellite 1-km resolution data.

When using composite optical satellite images for land studies, an accurate and sensitive method is needed to detect pixels contaminated by unwanted atmospheric and surface effects. In this paper, we have examined the feasibility of using an algorithm previously developed for postseason analysis but in a ‘forward’ mode, i.e. for identifying contaminated pixels in currentseason data. The CECANT ...
