Tropospheric methanol observations from space: retrieval evaluation and constraints on the seasonality of biogenic emissions
Methanol retrievals from nadir-viewing spacebased sensors offer powerful new information for quantifying methanol emissions on a global scale. Here we apply an ensemble of aircraft observations over North America to evaluate new methanol measurements from the Tropospheric Emission Spectrometer (TES) on the Aura satellite, and combine the TES data with observations from the Infrared Atmospheric ...

متن کاملAssessing known pathways for HO2 loss in aqueous atmospheric aerosols: Regional and global impacts on tropospheric oxidants
[1] We present a study of the potential importance of known reaction pathways for HO2 loss in atmospheric aerosols. As a baseline case, we calculate the reaction probability for HO2 loss by its self-reaction in aqueous particles. Detailed calculations assessed the effects of aerosol pH, temperature, particle size, and aqueous phase diffusion limitations on the rate of HO2 loss by this process. ...
متن کاملAssessment of the global impact of aerosols on tropospheric oxidants
[1] We present here a fully coupled global aerosol and chemistry model for the troposphere. The model is used to assess the interactions between aerosols and chemical oxidants in the troposphere, including (1) the conversion from gas-phase oxidants into the condensed phase during the formation of aerosols, (2) the heterogeneous reactions occurring on the surface of aerosols, and (3) the effect ...
