A microwave radiometer for the remote sensing of nitric oxide and ozone in the middle atmosphere
Read more of: A microwave radiometer for the remote sensing of nitric oxide and ozone in the middle atmosphereNitric oxide, which reacts catalytically to destroy ozone, can be produced in great abundance in the middle atmosphere during energetic particle precipitation triggered by solar storms. During the Antarctic winter, […]
