This master’s thesis investigates the advantages and disadvantages of deploying a spaceborne G-Band weather radar system, with a primary focus on its potential contributions to atmospheric profiling and cloud microphysics characterization. The study proposes that G-band radar, used in conjuction with other radar systems at lower frequencies (Ka and W Bands) that have already been deployed and demonstrated in space, can offer improved microphysical retrievals of hydrometeor size, scattering properties and hydrometeor water content. G-Band operates at higher frequency than conventional cloud radars at Ka-Band, thus working mainly in the non Raileygh regime it could unlock new possibilities in profiling high altitudes ice cloud, super cooled liquid water clouds and precipitating snow.
