MIDC: NREL Outdoor Spectral Data

NREL Outdoor Spectral Data

LI-COR LI-1800, Prede PGS-100, and EKO MS-700 Spectroradiometers are collecting
spectral data from approx. 300 to 1100nm, every 1 or 5 minutes during the day.
The AOCS is generating spectral data from 300 to 4000nm,
every 60 seconds when the AOCS parameter is less than 0.25.

The usable spectral range of the instrument is 300 to 1000nm.
The instrument was calibrated against NIST Standard of Spectral Irradiance F620 on September 3, 2009.
Known instrument problems can be found in the Data Quality Statements (DQS) database.
Instrument calibration history and reports are available in the AIM calibration database.
The instrument cleaning maintenance history since November 2004 is also available.
Measurements are made using the standard cosine receptor.

Direct Normal LI-1800 (S/N PRS-158) information:

The instrument has 4nm spectral bandwidth and the detector is maintained at 40^oC.
