Estonian weather and climate data (CLIDATA)

Physical conditions in the atmosphere. Includes spatial data resulting from measurements and modelling or from a combination of the two methods. Weather conditions and their measurement; air pressure, air temperature, precipitation, relative humidity, average wind speed and direction. Climate standards, i.e. long-term averages, calculated on the basis of a series of data for specific observatories of a certain length. The time length of the series is agreed, with thirty-year series of data as the standard worldwide, which also gives rise to the reference period for a given dataset — 1991-2020. The previous period of climate standards was 1981-2010.
