The two instruments operate differently and are therefore a good check of value agreement. 10 meter ocean wind speeds are measured by the radiometers, and wind vectors (speed and direction) are measured by WindSat (a polarimetric radiometer) and all scatterometers. Units of measurement are meters...

Radiation is defined as a value of the average radiance (Radiance) in a certain area rather than for each pixel. In particular, the clear-sky radiation (CSR) calculates the average value in a certain area using only the clear-sky region of the pixel in the observed values for respective ...
context along with the significantly reduced number of photons detected in the zenith at large source distances. As the source distance increases from 1.3 km to 3 km, 7 km, and 15 km, the zenith NSB in a turbid atmosphere falls to 26%, 5% and 0.4% of its starting value, respectively;...

It was found that the changes in the state of the night sky are best described by the derivative of the Sa value over time T, because just such derivative informs about how rapidly the Sa changes. We have sets of discontinuous measurements, so in this case, the discrete derivative dSa/dT...
