As precipitation from weather simulation data can show substantial deviations, the implementation of measurements is of major importance to reach the highest accuracy level. Real time observations from radar systems are used for precipitation nowcasting. To estimate historical precipitation there are data composites from satellites and measurement stations.

Historical precipitation data: Datasets

The following historical datasets, can be accessed with the meteoblue Dataset API:

IMERG Daily precipitation history, worldwide
CMORPH (NOAA) Hourly precipitation history, worldwide
CHIRPS2 (CHG) Daily precipitation history, worldwide
ARC2 (NOAA) Daily precipitation history for the African continent
LATAMCOSCH Daily precipitation history for Latin America
CPCGBA-US Daily precipitation history for the US

More details can be found in the technical documentation.

Real time precipitation: Radar animation with nowcasting

Precipitation nowcast data shows weather data for the present and near future (1-2 hours). These are observed with radar and show the best information available for the current conditions. meteoblue combines radar data from various sources in its seamless radar animations, that are available for any location worldwide.

The meteoblue weather forecasts (Package API) obtained by the meteoblue API will always include satellite, radar and measurement data automatically, if those data are available for the selected location. The accuracy of a precipitation nowcast is highly dependent on the availability, resolution and delay of the radar data, which differs for each country. An overview of the availability of real time radar data is given in our technical documentation.
