However, the Midwestern Regional Climate Center (MRCC) in partnership with the Western Regional Climate Center (WRCC) created a web services portal called Cli-DAP where NCEI hourly-observed data became easily accessible. As part of an NCEI additional work request, the MRCC produced a climatology of Heat Index and Wind Chill for the continental United States as a result of the increased data accessibility. In this dataset, stations files throughout the U.S. include threshold climatologies for various relevant thresholds. Individual years are also available for each threshold in these files. For heat index, probabilities of a certain heat index threshold are also available. These climatologies were produced under an additional work request for the NOAA/NCEI Regional Climate Center program. These climatologies show a proof of concept that data that are only observed on an hourly time-step can be accessed through Cli-DAP to produce robust climatologies that are not readily available through NOAA/NCEI products.
