Seasonal Trend Analysis

This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal trends expressed per year, over the selected period or percent of the average over the selected period.

Rainfall time series (1981-2020) and temperature time series (1961-2020) reconstructed from station observations, remote sensing and other proxies.

Dataset Documentation

Reconstructed rainfall and temperature data over land areas on a 0.0375 x 0.0375 lat/lon grid (about 4 km of resolution). The rainfall time series (1981 to 2020) were created by combining quality-controlled station observations with satellite rainfall estimates. Minimum and maximum temperature time series (1961 to 2020) were generated by combining quality-controlled station observations with downscaled reanalysis product.
