Kipp & Zonen pyranometers (Kipp & Zonen 2004) and pyrgeometers (Kipp & Zonen 2001), modified to make them better suited for use on an aircraft, measured the SW and LW irradiances.
At the Intercomparison, pyranometers, pyrgeometers, UVB radiometers, shadowband radiometers and a total sky imager (TSI) were located on the platform.
Silicon-domed Eppley PIR pyrgeometers, installed at 2 m above a grassy surface, were used as receivers of longwave radiation.
The net radiation measured by the pyranometers represents net shortwave (or solar) radiant flux, and the net radiation measured by the pyrgeometers represents net longwave (or far infrared) radiant flux.
The 95% response time for the pyranometers and pyrgeometers is about 18 seconds.
On the other hand, the pyrgeometers used for longwave radiation measure radiant heat fluxes in the far infrared spectrum (5-50 [micro]m).
Pyranometers, measuring in- and outgoing shortwave radiation and diffuse radiation, and pyrgeometers, measuring ingoing and outgoing longwave radiation, were mounted on a sawhorse-type structure (Fig.
