MERRA-2 meteorological re-analysis *DEMO*

This *DEMO* web service, available worldwide thanks to the interactive maps below, delivers time series of Temperature, Relative Humidity, Pressure, Wind speed and direction, Rainfall, Snowfall, Snow depth and Global Horizontal Irradiation (GHI).
Time steps range is from 1 min and up to 1 month (original data are hourly). Spatial resolution of approx. 50 km. Data are available for years 2004 to 2006 through this *DEMO* map.

MERRA-2 was introduced in 2016 to replace the original MERRA dataset because of advances made in assimilation system (MERRA stands for Modern-Era Retrospective analysis for Research and Applications).

To access the whole MERRA-2 dataset, you must be logged in and have a running subscription. Please contact us at if you need more information.
