The scanning radars (NPOL, D3R, DOW, and EC X band) operated through mid-January (with a Christmas break for the U.
The Ka-/Ku-band dual-frequency D3R radar has especially high resolution and sensitivity.
Example of an RHI of Ka-band reflectivity observed by the D3R radar in an azimuth directed from the coast (range 0 km) toward the Quinault valley at 1828 UTC 18 Dec 2015.
The decomposition equation used for CQESTR contains only one more term (fB, a biomass or residue type factor) than D3R.
The D3R model provided the proving ground for this process to allow for differing decomposition rates of residues with different initial nitrogen contents.
