International Meteorological Organization (IMO) Prize
The IMO Prize originates from the International Meteorological Organization, the predecessor to WMO. The IMO Prize is awarded annually. The first was presented to Dr Th. Hesselberg of Norway in 1956.

The IMO Prize includes:
- A 14-carat gold medal 57 mm in diameter. It bears on one side the official WMO emblem and on the other side the Latin inscription Pro singulari erga scientiam meteorologicam merito
- A monetary award of 10 000 Swiss francs
- A parchment scroll
Guidelines
Initially, the IMO Prize was granted in recognition of outstanding contributions in the field of meteorology. However, when the WMO mandate came to include operational hydrology in 1971, the range of IMO Prize expanded to include hydrology. Today, the IMO Prize covers any other field referred to in Article 2 of the WMO Convention.
Candidates for the IMO prize must be living persons; however, the award may be made posthumously to a candidate who dies between the date of his nomination and that of the awarding of the Prize.
Members of the Executive Council, as electors, are not eligible for the award during their term(s) of office.
