Data from: The Centennial Trends Greater Horn of Africa precipitation dataset

East Africa is a drought prone, food and water insecure region with a
highly variable climate. This complexity makes rainfall estimation
challenging, and this challenge is compounded by low rain gauge densities
and inhomogeneous monitoring networks. The dearth of observations is
particularly problematic over the past decade, since the number of records
in globally accessible archives has fallen precipitously. This lack of
data coincides with an increasing scientific and humanitarian need to
place recent seasonal and multi-annual East African precipitation extremes
in a deep historic context. To serve this need, scientists from the UC
Santa Barbara Climate Hazards Group and Florida State University have
pooled their station archives and expertise to produce a high quality
gridded ‘Centennial Trends’ precipitation dataset. Additional observations
have been acquired from the national meteorological agencies and augmented
with data provided by other universities. Extensive quality control of the
data was carried out and seasonal anomalies interpolated using kriging.
This paper documents the CenTrends methodology and data.
