XDS: NOAACRN

The U.S. Climate Reference Network (USCRN) is a network of climate stations that is being developed as part of a National Oceanic and Atmospheric Administration (NOAA) initiative. The first station was installed in Nov 2000 and as of the end of October 2008, 114 stations have been installed (113 in the United States and 1 in Canada. For future station information, see CRN’s latest newsletter). Its primary goal is to provide future long-term homogeneous observations of temperature and precipitation that can be coupled to long-term historical observations for the detection and attribution of present and future climate change. This datastream provides data from the station located at Barrow, Alaska and from two stations at Stillwater, OK.

Click on a measurement to see how CRN derives each value.

• Surface air temperature average for last 5 minutes of previous hour (C)
• Total amount of precipitation recorded during the previous hour (mm/hr)
• Downwelling Shortwave Hemispheric Irradiance, Pyranometer (W/m^2)
• Surface Infrared Temperature (K)

CRN provides their own QC values for Downwelling Shortwave Hemispheric Irradiance and for Surface Infrared Temperature.

The qc flags are as follows:

• 0 means good
• 2 means suspect
• 3 means erroneous

For Barrow, AK:
The data began on 2002-08-09.

For Stillwater, OK:
The data began on 2002-03-12.

The newest data are available with a 3-day delay.

Currently data are only available for the Barrow, Alaska site and two stations at Stillwater, Oklahoma.
