The climate atlas is a tool to help visualise climate datasets for Europe and Latvia.

Date & Time
Meteosat, Metop, NOAA

The SAF on Climate Monitoring (CM SAF) provides satellite-based climate information on a variety of parameters, which can help people find out something more about atmosphere and climate.

The climate atlas is a tool to help visualise climate datasets for Europe and Latvia. It is also a guide for working with satellite data in climatology.

More information and detailed analysis of the tool can be found in the In Depth section.

The atlas is based on the climate datasets provided by the CM SAF. It consists of maps providing climatological information of different meteorological parameters.

These include:

  • general climatic characteristics of meteorological parameters over Europe and Latvia;
  • information on satellite data suitable for climatological studies, particularly datasets provided by the CM SAF;
  • an example of the strengths and weaknesses of satellite data for climate applications;
  • instructions for creating a satellite climatology atlas and beginning to work with satellite datasets in general.

This tool should be used for viewing example data from different CM SAF climate datasets. The complete instructions provided here will enable users to create their own atlas with only minor additional support in processing or climatological theory.

In order to start creating your own atlas (or other product of your own choice), you should:

  1. Decide what you want to achieve.
  2. No, really decide what you want to achieve.
  3. Decide which CM SAF product is suitable for your application. In order to do this, you may want to consult the description files provided here and to visit the CM SAF web page and the Web User Interface.
  4. Order and download the data of interest by using the instructions for data ordering.
  5. Install the software and get an idea of how it works, get acquainted with the scripts. Use the instruction files provided here for a basic overview and guidance.
  6. Get acquainted with the work package (folder structure) and start working.
  7. Pay attention to the results you get. Is there something suspicious or artificial in the data? You may need to decide if you are looking at something geophysical (real) or something from the data and data processing.

Additional sources to help you:

  • Climate Atlas User Manual
  • For additional information on the atlas please contact from the Latvian Environment, Geology and Meteorology Centre (
  • For any additional support on the use of CM SAF data please .
  • CM SAF Community Site will provide you with tutorial videos and useful scientific discussions of the current users of the data
  • CM SAF Event week, webcasts (Climate Monitoring SAF and CM SAF Future Plans) and Training Modules (Satellite Data in Climate Monitoring) on the use of satellite data for climate monitoring
  • Online courses on computing and data analysis. You can find such courses on, for example, Coursera and Code School

Work package used to create the atlas:

Toolbox containing the folder structure, example scripts and data (9 Gb). It contains the required folder structure, scripts and example netCDF files for each product. Important – these are not the raw data as ordered and downloaded from the CM SAF archive, but the result files acquired through manipulation of the raw data.
