Retrieval algorithms for atmospheric attenuation in the frequency band 15–52 GHz from two-channel microwave radiometer observations
Conference contribution, 2019
Retrieval algorithms for atmospheric transmission, signal propagation path delay, atmospheric water
vapour and liquid water contents have been produced within the context of a prototype development of
a dual-channel microwave radiometer. The errors found match what is achieved by existing radiometers.
The requirement formulated by ESA for the transmission retrieval is met. In fact, this requirement is met
with some margin allowing for additional offset errors in the atmospheric attenuation coefficients and in the
two radiometer channels which have not been included in the simulations.
