The WMO hierarchy:
The annually published WMO Statements on the status of the World Climate provides details of global, regional and national temperatures and extreme weather events. It also provides information on long-term climate change indicators include atmospheric concentrations of greenhouse gases, sea level rise, and sea ice extent. The year 2016 was the hottest year on record, with many weather and climate extremes, according to the most recent WMO report.
In keeping with its mandate to promote the standardization of meteorological observations, the WMO maintains numerous code forms for the representation and exchange of meteorological, oceanographical, and hydrological data. The traditional code forms, such as SYNOP, CLIMAT and TEMP, are character-based and their coding is position-based. Newer WMO code forms are designed for portability, extensibility and universality. These are BUFR, CREX, and, for gridded geo-positioned data, GRIB.
As of February 2014, WMO Members include a total of 185 Member States and 6 Member Territories.
