USCRN Overview .

The U.S. Climate Reference Network ( USCRN ) consists of 114 stations developed, deployed, managed, and maintained by the National Oceanic and Atmospheric Administration ( NOAA ) in the continental United States for the express purpose of detecting the national signal of climate change. The vision of the USCRN program is to maintain a sustainable high-quality climate observation network that 50 years from now can with the highest degree of confidence answer the question: How has the climate of the nation changed over the past 50 years ?


The U.S. Regional Climate Reference Network ( USRCRN ) pilot project was deployed in the Southwestern U.S. by NOAA during the period 2009-2011. These stations were designed to provide the same level of climate science quality measurements as the national-scale U.S. Climate Reference Network (USCRN), but are spaced more closely, and focus solely on temperature and precipitation.  In accordance with Service Change Notice 14-25 from the National Weather Service , NCDC will stop providing data from the 72 Southwest Regional Climate Reference Network stations on or about June 1, 2014. The historical data for these stations will remain available. This change does not affect any station in the Climate Reference Network.


Now, examine the plot shown above.
To eliminate any claims of “cherry picking” the time period, the selected range to be from 2004 through 2014, is the FULL range of data ( current to beginning ), no data exists prior to January 2005. NOAA/NCDC does not make any data from the USCRN available prior to 2005, because there were not enough stations in place yet to be representative of the Contiguous United States. What you see is the USCRN data record in its entirety, with no adjustments, no start and end date selections, and no truncation. The only thing that has been done to the monthly average data is gridding the USCRN stations, so that the plot is representative of the Contiguous United States.  Go look for yourself :
