14th Conference on Applied Climatology


Development of the 1971–2000 monthly station climate summaries (Climatography of the United States NO. 20 or CLIM20)

Tom Whitehurst, NOAA/NESDIS/NCDC, Asheville, NC

NOAA’s National Climatic Data Center (NCDC) has recently completed a new suite of Monthly Station Climate Summaries for the 1971-2000 period of record. These station summaries are of particular interest to agriculture, industry and engineering applications and include a variety of statistics for temperature, precipitation, snow, and degree day elements for 4,263 stations. The new CLIM20 updates and expands on the previous version (1,879 stations) which was last published in 1985 and covered the period 1951-1980. The types of statistics include means, median (precipitation and snow elements), extremes, mean number of days exceeding threshold values, and probabilities for monthly precipitation and freeze data. There is also a table for each station with heating, cooling, and growing degree days for various temperature bases. This poster will illustrate several of the new CLIM20 products.
