Diurnal variations of humidity and ice water content in the tropical upper troposphere
humidity and ice water content the tropical upper troposphere
font style='font-size:12px;'>
2010/12/20
Observational results of diurnal variations of humidity from Odin-SMR and AURA-MLS, and cloud ice mass from Odin-SMR and CloudSat are presented for the first time. Comparisons show that the retrievals...
Effects of relative humidity on aerosol light scattering in the Arctic
