==== NISTAR ====
The National Institute of Standards and Technology Advanced Radiometer (NISTAR) was designed and built between 1999 and 2001 by NIST in Gaithersburg, MD and  [[Ball Aerospace & Technologies]] in [[Boulder, Colorado]]. NISTAR measures irradiance of the sunlit face of the Earth. This means that NISTAR measures if the [[atmosphere of Earth]] is taking in more or less solar energy than it is radiating back towards space. This data is to be used to study changes in Earth's [[radiation budget]] caused by natural and human activities.<ref name=noaa_nistar>{{cite web| title= NOAA Satellite and Information Service: Deep Space Climate Observatory (DSCOVR): National Institute of Standards and Technology Advanced Radiometer (NISTAR)|url=http://www.nesdis.noaa.gov/DSCOVR/pdf/DSCOVR%20-%20NISTAR%20Instrument%20Info%20Sheet.pdf| publisher=NOAA|access-date= February 10, 2015|url-status= dead |archive-url= https://web.archive.org/web/20150422070911/http://www.nesdis.noaa.gov/DSCOVR/pdf/DSCOVR%20-%20NISTAR%20Instrument%20Info%20Sheet.pdf|archive-date=April 22, 2015}} {{PD-notice}}</ref>

Using NISTAR data, scientists can help determine the impact that humanity is having on the atmosphere of Earth and make the necessary changes to help balance the radiation budget.<ref>{{cite web |url= http://www.nasa.gov/content/goddard/noaas-dscovr-nistar-instrument-watches-earths-budget|title=NOAA's DSCOVR NISTAR Instrument Watches Earth's "Budget"|publisher=NASA|last=Jenner|first=Lynn|date=January 20, 2015|access-date=March 12, 2019}} {{PD-notice}}</ref> The radiometer measures in four channels:
* For total radiation in [[ultraviolet]], [[Visible spectrum|visible]] and [[infrared]] in the range 0.2–100&nbsp;μm
* For reflected solar radiation in the ultraviolet, visible and near-infrared in the range 0.2–4&nbsp;μm
* For reflected solar radiation in infrared in the range 0.7–4&nbsp;μm
* For calibration purposes in the range 0.3–1&nbsp;μm
