HIRLAM model runs have ended
The use of the HIRLAM weather forecasting model at the Finnish Meteorological Institute has been ended in the end of October 2022, after which its forecasts are not available through the open data services. HARMONIE (MEPS) forecasts are available through the our open data services.
During the past fifteen years, the main focus in forecast model development has been on a more accurate model with improved resolution. The resulting HARMONIE (MEPS) model is capable of 2.5 km horizontal resolution (compared to 7.5 km of HIRLAM) and able to predict small scale phenomena more accurately. HARMONIE (MEPS) forecasts are now available through the open data services.
Tools to handle the data
The data is stored in GRIB2-files. Below is listed few possible tools to handle the data.
PanoPly provides an easy UI to view GRIB, NetCDF and HDF files.
Integrated Data Viewer (IDV)
Compared to PanoPly Integrated Data Viewer (IDV) provides a slightly more complicated but more versatile user interface for browsing and analysing geographical data.
Bunch of tools exist for batch processing the data:
ECMWF GRIB tools provides number of convenient command line tools to process the data. For more information, please consult their wiki:
Geospatial Data Abstraction Library GDAL supports GRIB as well
If you are using the data in an operational manner and live in web environment, SmartMet Server is a great resource to extract the data as JSON or GML and visualize it via WMS.
