Mapping annual mean ground-level PM2.5 concentrations using Multiangle Imaging Spectroradiometer aerosol optical thickness over the contiguous United States
[1] We present a simple approach to estimating ground-level fine particulate matter (PM2.5, particles smaller than 2.5 mm in diameter) concentrations by applying local scaling factors from a global atmospheric chemistry model (GEOS-CHEM with GOCART dust and sea salt data) to aerosol optical thickness (AOT) retrieved by the Multiangle Imaging Spectroradiometer (MISR). The resulting MISR PM2.5 co...
متن کاملValidation of Multiangle Imaging Spectroradiometer (MISR) aerosol optical thickness measurements using Aerosol Robotic Network (AERONET) observations over the contiguous United States
[1] Aerosol optical thickness (AOT) data retrieved by the Multiangle Imaging Spectroradiometer (MISR) in 2001 were compared with AOT measurements from 16 Aerosol Robotic Network (AERONET) sites over the contiguous United States. Overall, MISR and AERONET AOTs were strongly correlated (r = 0.73). Regression analysis showed that the root mean square error (RMSE) of MISR AOT was 0.05. The overall ...
متن کاملValidation of MISR Aerosol Optical Thickness Measurements Using AERONET Observations over the Contiguous United States
Aerosol optical thickness (AOT) data derived by the Multi-angle Imaging SpectroRadiometer (MISR) from Jan 2001 to Feb 2002 were compared with AOT measurements from 16 Aerosol Robotic Network (AERONET) sites over the contiguous United States. Overall, MISR and AERONET AOTs were strongly correlated (correlation coefficient = 0.81). Regression analysis showed that MISR AOT retrievals had a positiv...
متن کاملAerosol optical thicknesses over North Africa: 1. Development of a product for model validation using Ozone Monitoring Instrument, Multiangle Imaging Spectroradiometer, and Aerosol Robotic Network
[1] Daily aerosol optical thickness (AOT) at 0.55 mm over the desert regions is needed as a source of validation for numerical models such as the United Kingdom’s Numerical Weather Prediction Unified Model. We examined the relationship between monthly mean ultraviolet (UV) absorbing aerosol index (AI) from the Ozone Monitoring Instrument (OMI) that is available on a daily basis with the Multian...
متن کاملGlobal aerosol optical properties and application to Moderate Resolution Imaging Spectroradiometer aerosol retrieval over land
[1] As more information about global aerosol properties has become available from remotely sensed retrievals and in situ measurements, it is prudent to evaluate this new information, both on its own and in the context of satellite retrieval algorithms. Using the climatology of almucantur retrievals from global Aerosol Robotic Network (AERONET) Sun photometer sites, we perform cluster analysis t...
