Rainfall and temperature time series reconstructed from station observations and remote
sensing proxies. This interface allows users to view rainfall, maximum, minimum and
mean temperature dekadal climatologies and anomalies. The climatology is defined over
the period 1991 - 2020 .

The Maproom facilitates the exploration of the history of extreme monthly and seasonal
rainfall characteristics.

The Standardized Precipitation Index is an indicator of extreme rainfall events, whether
they are drought or excess rainfall.

This map shows the historical probability (given in percentile) of seasonal average
monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry)
one-third ("tercile") of the 1991-2020 historical distribution in Nigeria given the
state of ENSO (El Niño, Neutral, La Niña) during that same season.
