Multifilter Radiometer (MFR)
Instrument Categories: Radiometric
General Overview
The multi-filter radiometer (MFR) is simply the head from a multi-filter rotating shadowband radiometer (MFRSR) mounted on a tower pointing at the surface. Like the MFRSR, it has six narrowband channels (415, 500, 615, 673, 870, and 940 nm) and one broadband channel. Pointing the head at the surface provides spectral measurements of reflected irradiance. Measurements are taken every 20 seconds. No averaging is performed.
Primary Measurements Taken
The following measurements are those considered scientifically relevant. Refer to the netCDF File Header Descriptions (Data Object Design Files) for the list of all available measurements, including those recorded for diagnostic or quality assurance purposes.
- Shortwave narrowband diffuse upwelling irradiance
- Shortwave narrowband total upwelling irradiance
- Surface albedo
Available Datastreams
- mfr10m - Multi-Filter Radiometer (MFR): upwelling irradiance at 10-meter height
- mfr25m - Multi-Filter Radiometer (MFR): upwelling irradiance at 25-meter height
