- The National Oceanographic and Atmospheric Administration (NOAA) is responsible for the operation, documentation and upkeep of the United States Historical Climatological Network (USHCN) set of weather stations. In 1997 a National Research Council panel expressed concerns about the state of the network and its ability to acquire data suitable for climate monitoring. Despite continuing complaints for ten years, no systematic efforts were made even to document the condition of the network. Finally, in 2007 after discovering several stations totally out of compliance with published standards, meteorologist Anthony Watts organized a grassroots effort with a network of hundreds of volunteers to survey and photograph all 1221 stations in the USHCN. This project, currently in progress, led to the creation of the ["surfacestations.org"] [http://www.surfacestations.org/] website. Because very little current physical site condition data exists in the public domain, the goals of the project are:	+ The National Oceanographic and Atmospheric Administration (NOAA) is responsible for the operation, documentation and upkeep of the ["United States Historical Climatological Network"] (["USHCN"]) set of weather stations.

- As of November 2007 about one third of the USHCN station sites had been surveyed. Preliminary analysis of the data show a substantial number of stations are compromised by nearby structures, vegetation, asphalt parking lots, and unnatural heat sources such as air conditioning exhaust, automobiles, and barbeque grills.

Preliminary analysis of the data show a substantial number of stations are compromised by nearby structures, vegetation, asphalt parking lots, and unnatural heat sources such as air conditioning exhaust, automobiles, and barbeque grills. These "microsite" problems have been assessed using [french study] that ranks the station quality on a scale of 1 (high quality) to 5 (low quality). Using the currently surveyed USHCN stations, only four percent qualify as "1" and only nine percent qualify as "2".

- The surface station temperature record consists of a collection of daily thermometer readings from locations all around the world, with the record going back up to 150 years in some locations. Most records are far shorter, with the longest and most extensive coming from the continental U.S. These temperature recordings are used as inputs into or validation against some climate models. If the records are combined into annual average temperatures, they can be used to show changes in temperature over time. It is generally accepted in the climate community that the world has warmed about .8 degrees Celsius in the past century with relative warming until the late 1930s, cooling until the 1970s, and then warming again afterward.	+ The surface station temperature record consists of a collection of daily thermometer readings from locations all around the world, with the record going back up to over 150 years in some locations.
