Long-term observing stations

Long-term observing stations

"These long-term measurements ... are the backbone of both weather forecasting and climate science. It is highly important that we ensure the long-term sustainability of these measurements."

 Prof. Petteri Taalas, Secretary-General, World Meteorological Organization


Long-term meteorological observations are part of the irreplaceable cultural and scientific heritage of mankind that serve the needs of current and future generations for long-term high quality climate records. They are unique sources of past information about atmospheric parameters, thus are references for climate variability and change assessments. To highlight this importance, WMO has a mechanism to recognize long-term observing stations. By so doing, the Organization promotes sustainable observational standards and best practices that facilitate the generation of high-quality time series data.

The mechanism involves close collaboration between the Commission for Climatology (CCl), the Commission for Basic Systems (CBS), the Commission for Instruments and Methods of Observations (CIMO), the Global Climate Observing System (GCOS), the WMO Secretariat and Members. The May 2017 WMO Executive Council meeting recognized a first set of WMO long-term observing stations (see Recognized stations below). Another call for the nomination of candidate stations will be issued by WMO in early 2018.
