Dear Dr. Hulme:
Would you be willing and available to review "Vegetation index trends for the African Sahel 1982-1999" by Lars Eklundh, Lennart Olsson, submitted for possible publication in the Geophysical Research Letters.
The manuscript's abstract is:
Pathfinder AVHRR NDVI data have been analyzed for the African
Sahel to study recent trends in vegetation greenness. A strong
increase in seasonal NDVI was observed over large areas in the
Sahel during the period 1982-1999. The increase is interpreted
as a vegetation recovery from the drought periods of the 1980's.
Although strong shifts in satellite overpass times have led to
shifting solar zenith angles (SZA) over the time period, only
minimal influence of SZA's on the Pathfinder NDVI was found in
our data. A preliminary analysis of rainfall data indicates
increasing rainfall during the period. The observed trends may
have important implications to the Sahel including changes to
the water cycle, energy exchange and carbon storage.
