nClimDiv Station Inventories March 2014 Divisional inventory files are located in the main CIRS nClimDiv directory: ftp://ftp.ncdc.noaa/gov/pub/data/cirs/climdiv and have the following naming conventions: climdiv-(ak-)prcp-inv-recent-vX.Y.Z-YYYMMDD climdiv-(ak-)tmax-inv-recent-vX.Y.Z-YYYMMDD climdiv-(ak-)tmin-inv-recent-vX.Y.Z-YYYMMDD climdiv-(ak-)prcp-inv-vX.Y.Z-YYYYMMDD climdiv-(ak-)tmax-inv-vX.Y.Z-YYYYMMDD climdiv-(ak-)tmin-inv-vX.Y.Z-YYYYMMDD where: X,Y,Z represents a version number (i.e. 1.0.0 for the initial release) YYYMMDD represents the year/month/day data were processed Inventory files which include *recent* in the name are comprised of stations used to compute ClimDiv values for the most recent two calendar years. Data values and station information prior to this timeframe will not change unless the dataset undergoes a version change. For a station to be included in the divisional mean temperature data set, it must be included in both tmax and tmin inventories. Alaska inventory files are separate from CONUS. They are named with a similar convention but with an "ak" included.

The Atmore station is located at latitude 31.1819N and longitude 87.4389W, within Alabama Climate Division 7 (107, state number 1, division number 7). Note that climate division values are influenced by information from stations in neighboring areas, and are not a straight average of the station within them.
