Instrument: FAAM Pyrgeometer 4-50 um BBR

Name FAAM Pyrgeometer 4-50 um BBR
Acronym Pyrgeometer-4-50um-FAAM
Manufacturer Met Office
Operated by FAAM
Operated onboard

Instrument type

Name Broad Band Radiometer
Acronym BBR

Principle of operation

Measured parameter Hemispheric broadband radiance
Operating principle

Measures up-welling and/or down-welling incident radiation in visible/near infra-red

Measurement(s) Radiation

Dimension and weight

External dimension 160mm long 202mm diameter. Logging unit 135x140x230mm
Weight 0.0


Operating mode Remote sensing






Upper and lower facing PYRGEOMETER (4-50 microns) fitted with silicon dome. Identical instruments fitted on top and below aircraft to measure broadband hemispheric infrared radiation.

Operational restriction

The instruments should be horizontal to within 3degrees when the aircraft is flying at the mean angle of attack. Airflow past the radiometer bodies is required to reduce thermal stabilization times

Operational requirements

The requirement is for a location with a minimum of obstruction to the hemispheric field of view of the radiometers, preferably away from radio transmitter antennas

Certification approvals

Approved by CAA for use on BAe 146-301.
