Validation and comparison of cloud properties retrieved from passive satellites over the Southern Ocean [PDF]
The clouds over the Southern Ocean (SO) play a vital role in defining the Earth's energy budget. The cloud properties over the SO are known to be different from their Northern Hemisphere counterparts. As a result, monitoring cloud properties over the SO,

Changing patterns of global-scale vegetation photosynthesis, 1982-1999 [PDF]
The primary objective of this research was to assess changes in global vegetation photosynthesis between 1982 and 1999. Global-scale Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data from the Pathfinder ...

Abstract The Satellite Data Services Division (SDSD) maintains a digital browse file of Advanced Very High Resolution Radiometer (AVHRR) data. The AVHRR instrument is aboard the TIROS‐N series of spacecraft. The instrument has five channels for viewing the earth, two channels are in the visible part of the spectrum and three are in the infrared portion

Estimation of spatio-temporal distribution of precipitable water using MODIS and AVHRR data: a case study for Cyprus [PDF]
In this paper, the atmospheric precipitable water (PW) over the area of Cyprus was estimated by means of Advanced Very High Resolution Radiometer (AVHRR) thermal channels brightness temperature difference (ΔT).

Bergmann's rule: Why does body size increase with latitude?
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bergmann's rule describes the tendency for endothermic body size to increase with latitude, a pattern often attributed to climatic factors. However, the underlying developmental and evolutionary mechanisms remain debated.
