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 ...

Abstract Previous studies have documented substantial advancing trends in the onset date of vegetation green-up (VGD) during 1980s and 1990s over Northern Hemisphere, while later based on data from spaceborne advanced very high-resolution radiometer (AVHRR) reported this trend stalled warming hiatus late to early 2010s. However, there is uncertainty finding a VGD advance due identification qual...

Scientists at CSIRO (Australia) engage in a coordinated group of related projects involving land surface reflectance anisotropy. One of the underlying themes of the work is to test/establish the existence of a stable underlying “typology” of BRDF directly attributable to land surface spectral and structural parameters that will allow sensible selections of the “shape functions” used in correcti...

The European Space Agency project for studies of cloud properties in the Climate Change Initiative programme (ESA-CLOUD-CCI) aims at compiling the longest possible time series of cloud products from one single multispectral sensor—The five-channel Advanced Very High Resolution Radiometer (AVHRR) instrument. A particular aspect here is to include corresponding products based on other existing (M...
