What's new vs. Meteonorm 8

Meteonorm Version 9 includes the following major news:

• Complete refactoring of the calculation core, web service / API and user interface. Transfer of the user interface from a desktop application to a web application.

• New main climate period for radiation, temperature and other meteorological parameters: 2001 – 2020.

• New station data from newly accessible open sources (primarily from national meteorological services adopting open data policies).

• Enhanced quality and quality control mechanisms for surface observations.

• New satellite data: MSG 2008 – 2023, IODC, Himawari and GOES-E: 2018 – 2023.

• Local improvement of Meteotest’s global satellite model.

• Improved blending surface observations and satellite data.

• Introduction of new IPCC AR6 scenarios (SSP1-2.6, SSP2-4.5 and SSP3-7.0). The average of 15 global climate models of CMIP6 will be included. 10-year averages for 2030 – 2090 will be stored and accessible.

• More inherent integration of historical time series.

• The topography data is now based on the Copernicus GLO-30 digital elevation model, which is globally available and has a higher spatial resolution (30m) than the previously used SRTM dataset (90m resolution).

• The aerosol and Linke turbidity information has been updated. New climatologies based on Merra2¹ and the reference period of 2001 - 2020 are used instead of the blended dataset (Aeronet ground data, Merra2 and MODIS) in Meteonorm 8.
