ACE-ASIA: NSF/NCAR C-130 Spectral (TDDR) Measurements


This dataset contains radiation measurements made during ACE-ASIA on the C-130 aircraft. Archived data consists of two spectral narrowband radiometers (one uplooking and one downlooking). Each TDDR (Total-Direct-Diffuse Radiometer) had a hemispherical field-of-view, and a scanning shadowband was used (only on the uplooking instrument) to regularly block the sun thus allowing determination of the total, direct, and diffuse components of the radiation field. All data is in .cdf format.
