"The [Measurement and Instrumentation Data Center (MIDC)](https://midcdmz.nrel.gov/) is operated by NREL and provides irradiance and meteorological data from a number of ground stations in the U.S. The stations vary in quality, with some stations measuring all three components with high-quality instruments and other stations featuring a rotating shadow band pyranometer.\n",
"\n",
"The most notable station is the [Baseline Measurement System (BMS)](https://midcdmz.nrel.gov/apps/sitehome.pl?site=BMS) at NREL's [Solar Radiation Research Laboratory (SRRL)](https://www.nrel.gov/esif/solar-radiation-research-laboratory.html) outside of Denver, Colorado. The BMS features the world's largest collection of operating pyranometers and pyrheliometers. A number of sky imagers, PV reference cells, and spectral radiometers are also located at the site. Instruments at the BMS are cleaned each weekday and frequently calibrated. Due to the large collection of co-located and well maintained instruments, the BMS data is ideal for comparing different types of instruments.\n",
"\n",
"Note, the MIDC includes several inactive stations. Also, several of the active stations are no longer cleaned or calibrated frequently. For these reasons, the SolarStations.Org catalog only includes the SRRL BMS, SOLARTAC, and Flatirons M2 sites, as these measures all three irradiance components and are active. See the map below for the locations of the stations."
