1. An apparatus, comprising:
a microwave sensor configured to operate at a V-band between a range of 51 and 71 GHz, producing high fidelity retrievals of one or more pressure and temperature profiles, Including obtaining vertical temperature information, wherein
the microwave sensor comprises a broadband transmitter and one or more receivers with three or more transmitted and received radar frequencies, the three or more transmitted and received frequencies are used to provide an estimate of atmospheric oxygen absorption in atmosphere, and
the microwave sensor is further configured to provide vertical pressure profiles by combining three radar frequency data from the three or more transmitted and received radar frequencies with vertical temperature information.
