Background

The World Weather Records (WWR) database contains historical monthly climatic data from land surface stations worldwide. First released in 1927, the WWR database has been widely employed in operational climate monitoring, international climate assessments, and numerous other applications. Data were supplied by National Meteorological Services of the WMO Members every 10 years. New approach for the annual submission of WWR has been adopted by World Meteorological Congress by Resolution 14 (EC-64).
World Weather Records can be accessed through the World Data Centre for Meteorology, National Centers for Environmental Information (NCEI), Asheville, United States at http://www1.ncdc.noaa.gov/pub/data/wwr/.
For further inquiries, WMO members are invited to contact WMO through the following email adress : wcdmp@wmo.int.

WWR Data includes monthly mean of the following climatic elements:

  • (Code 2) Monthly mean station pressure;
  • (Code 3) Monthly mean sea-level pressure;
  • (Code 4) Monthly mean temperature;
  • (Code 5) Monthly mean maximum temperature;
  • (Code 6) Monthly mean minimum temperature;
  • (Code 7) Total monthly precipitation.
  • Code 8) Monthly mean relative humidity. (monthly means of daily relative humidity can also be submitted).

    WWR includes also station metadata notes that document observation practices and station configurations.

    To address the capacity building needs, in National Meteorological and Hydrological Services (NMHSs) of Central and West Africa countries, and under the “West Africa Region: Seamless Operational Forecast Systems and Technical Assistance for Capacity Building (CREWS-West Africa)" Project, funded by the Climate Risk and Early Warning Systems (CREWS) initiative, the Moroccan Direction Générale de la Météorologie , in collaboration with the World Meteorological Organisation, organize two workshops on :
