Extreme weather records - Compilation, adjudication, and publication

The United States National Oceanic and Atmospheric Administration (NOAA) established in 1997 the National Climate Extremes Committee (NCEC) tasked to asses the scientific merit of extreme meteorological/ climatological events in the US. It is concerned with certain weather elements as snow, rain, temperature, wind, hail and atmospheric pressure. However, the organization is not concerned with regional or state records, but only of the national scale. However, when thinking of establishing an NCEC-like organization on a global scale, there are various curiosities that must be considered. For one, there is a concern on how much validity should be given to historical reports predating modern verification practices. Another is related to the geographical scale of the record and the proper note of the temporal boundaries for records. In addition, there is the concern on how weather archiving address distinct nonmeteorological trends in the data.
