Title:Guide to Hourly Surface Meteorological Data
Author(s):Petersen, Mary Schoen
Subject(s):Meteorology
National Climate Data Center
Abstract:The data are nearly identical to the original hourly surface observations as archived by the National Climatic Data Center (NCDC). The exceptions are the sky condition, cloud coverage, cloud type, and cloud height elements. Intuitively, the absence of an element for one or more hours would normally indicate missing data. However, close examination of the National Weather Service's MF1-10 forms from Springfield, Illinois (.e.g, 5 July 1951) in conjunction with NCDC's archived Springfield data, indicated that the absence of the sky condition element during an entire day is informative in itself, indicating no clouds to report that day. Therefore, this was assumed for all stations and is reflected in the data as "clear" (sky condition and cloud cover) and "none" (cloud type). Additionally, six layers of clouds were allowed for each hour. Thus, if fewer than 6 layers were reported, the values for layers above those reported were coded as "clear" or "none" (see Sections 1 and 3 of Chapter II for additional information).
