Simulation study for ground-based Ku-band microwave observations of ozone and hydroxyl in the polar middle atmosphere
free download

The Ku-band microwave frequencies (10.70 14.25 GHz) overlap emissions from ozone (O 3) at 11.072 GHz and hydroxyl radical (OH) at 13.441 GHz. These important chemical species in the polar middle atmosphere respond strongly to high-latitude geomagnetic Soil moisture is the key variable that controls the surface water movements including infiltration, evapotranspiration, and groundwater recharge. It is one of the most important surface conditions of the exchange processes between land and atmosphere. Microwave
