Knowledge of soil properties such as organic carbon content, clay content and pH is vital for agriculture and climate change analysis in Africa. ISRIC has launched a new type of freely accessible soil property maps for Africa. The maps contain predictions of seven soil properties at six standard depths at 1 km resolution. The soil property maps as well as the software to generate them are available for download under a Creative Commons licence.

Contains the following layers
a.    Clay
b.    Course fragment content  
c.    Rootzone depth
d.    Rootzone soil texture
e.    Sand content
f.    Soil Morphons
g.    Soter soil map
h.    Zambia soils.
 

Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 30+ year quasi-global rainfall dataset.
Spanning 50°S-50°N (and all longitudes), starting in 1981 to near-present, CHIRPS incorporates 0.05° resolution satellite imagery with in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.

GLDAS datasets are available from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC)

Oxygen Availability to Roots – Harmonized Soil Water Database

The Shuttle Radar Topography Mission (SRTM) was flown aboard the space shuttle Endeavour February 11-22, 2000. The National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA) participated in an international project to acquire radar data which were used to create the first near-global set of land elevations.

Global Digital Elevation Model (ASTGTM) was developed jointly by the U.S. National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). ASTER is capable of collecting in-track stereo using nadir- and aft-looking near infrared cameras.
