Climate Change And Snowmelt--Turn Up The Heat,But What About Humidity?
Climate Change Snowmelt Turn Up The Heat Humidity
2018/2/1
It’s said on sticky summer days: “It’s not the heat, it’s the humidity.” That holds true in the winter too, and could hold the key to the future of snowpack and water resources in the American West.In...
Diurnal variations of humidity and ice water content in the tropical upper troposphere
humidity and ice water content the tropical upper troposphere
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...
Influence of relative humidity and temperature on the production of pinonaldehyde and OH radicals from the ozonolysis of α-pinene
relative humidity and temperature pinonaldehyde and OH radicals α-pinene
2010/8/16
The ozonolysis of α-pinene has been investigated under dry and humid conditions in the temperature range of 243–303 K. The results provided new insight into the role of water and temperature in the de...

This paper uses radiosonde launches made by the UK Meteorological Office, from the British Isles, Gibraltar, St. Helena and the Falkland Islands between January 2002 and December 2006, to investigate ...
Organic particulate matter formation at varying relative humidity using surrogate secondary and primary organic compounds with activity corrections in the condensed phase obtained using a method based on the Wilson equation
Organic particulate matter formation surrogate secondary primary organic the Wilson equation
2010/8/13
Secondary organic aerosol (SOA) formation in the atmosphere is currently often modeled using a multiple lumped "two-product" (N·2p) approach. The N·2p approach neglects: 1) variation of activity coeff...
Effects of relative humidity on aerosol light scattering in the Arctic
relative humidity aerosol light the Arctic
2010/8/12
Aerosol particles experience hygroscopic growth in the ambient atmosphere. Their optical properties – especially the aerosol light scattering – are therefore strongly dependent on the ambient relative...
