General Data Description

NOAA/ESRL GMD (National Oceanic and Atmospheric Administration / Earth System Research Laboratory, Global Monitoring Division) provides surface radiation data from Barrow, AK, part of a long-term surface solar irradiance monitoring network of globally remote sites (G-Rad). Data are available from 1976-02-18 to present.

Data User Notes

The number of instruments and measurements taken has varied throughout the years.

All irradiances are 3 minute averages before 1998-01-01, 1 minute averages after this date.

Here are the date ranges and available measurements:
(Note: *** indicates new measurement when compared to the previous time period)

2002-10-29 / 2003-11-27:
Note: Upwelling Shortwave Hemispheric Irradiance mounted at 20m has been removed.

2003-11-28 / 2006-08-13:

Note: Upwelling data (see variables, Upwelling Shortwave Hemispheric Irradiance,Upwelling Longwave Hemispheric Irradiance, Upwelling Pyrgeometer Case Thermistor Temperature, Upwelling Pyrgeometer Dome Thermistor Temperature, including Battery #2 Voltage) is being recorded from a new albedo rack, which is at a higher location than the previous albedo rack.


2006-08-13 / present:

Additional measurements Shortwave Direct Normal Irradiance and Downwelling Shortwave Diffuse Hemispheric Irradiance were added for redundancy.
