This website was created in response to the realization that very little physical site survey data exists for the entire United States Historical Climatological Network (USHCN) and Global Historical Climatological Network (GHCN) surface station records worldwide. This realization came about from a discussion of a paper and some new information that occurred on Dr. Roger Pielke Sr. Research Group Weblog.

Mid term census report of the Surface Stations Project: Is the U.S. Surface Temperature Record Reliable? - click cover image at left to download a PDF document. Now at 80%, and with a majority sample that is spatially well distributed, a full analysis will be coming in the next few months. We will however continue to survey stations in the hope of locating more CRN1 and CRN2 stations due to their rarity.

The upcoming papers will feature statistical analysis of the nationwide USHCN network in the context of siting.
