Global Aerosol Climatology Project (gacp) Data Show the Potential Climate Impact of Aerosols
نویسنده
چکیده
The warming trend of the past decade may be related to increasing amounts of downward solar radiation reaching the Earth’s surface. Recent decreases in tropospheric aerosols may also have contributed via both direct and indirect aerosol effects. The green line (above) reveals a long-term decreasing tendency in the tropospheric aerosol optical thickness (AOT) and the red line shows the overall behavior of the GACP AOT (January 1986 – June 1991). The regional distribution of AOT for 2002–2005 is shown at the right and a regional comparison with 1988–1991 appears on page 16. See article by M. Mischenko and I. Geogdzhayer on page 4.

P2.52 Combining Satellite Data, Trajectory Modeling and Surface Insolation Measurements to Deduce the Direct Radiative Effect of Smoke Aerosol
The need to develop a climatology of aerosols and their direct radiative forcing has been identified as a critical gap in our knowledge of the earth’s atmosphere and may play a large role in the process of climate change. Recognizing this need, the Global Aerosol Climatology Project (GACP) was instituted by NASA and under the auspices of the World Climate Research Programme (WCRP)/ Global Energ...
متن کاملValidation of Long-Term Global Aerosol Climatology Project Optical Thickness Retrievals Using AERONET and MODIS Data
A comprehensive set of monthly mean aerosol optical thickness (AOT) data from coastal and island AErosol RObotic NETwork (AERONET) stations is used to evaluate Global Aerosol Climatology Project (GACP) retrievals for the period 1995–2009 during which contemporaneous GACP and AERONET data were available. To put the GACP performance in broader perspective, we also compare AERONET and MODerate res...
متن کاملValidation of the GRAPE single view aerosol retrieval for ATSR-2 and insights into the long term global AOD trend over the ocean
The Global Retrieval of ATSR Cloud Parameters and Evaluation (GRAPE) project has produced a global dataset of cloud and aerosol properties from the Along Track Scanning Radiometer-2 (ATSR-2) instrument, covering the time period 1995–2001. This paper presents the validation of aerosol optical depths (AODs) over the ocean from this product against AERONET sun-photometer measurements, as well as a...
متن کاملLong-term satellite record reveals likely recent aerosol trend.
Analysis of the long-term Global Aerosol Climatology Project data set reveals a likely decrease of the global optical thickness of tropospheric aerosols by as much as 0.03 during the period from 1991 to 2005. This recent trend mirrors the concurrent global increase in solar radiation fluxes at Earth's surface and may have contributed to recent changes in surface climate.
متن کاملBrief Accuracy Assessment of Aerosol Climatologies for the Retrieval of Solar Surface Radiation
Solar surface irradiance is an important variable in many different fields, e.g., climate monitoring and solar energy. Remote sensing data are nowadays well established and the only observational data source in many regions of the world. Aerosols significantly affect the clear sky radiation and hence also the all sky radiation. In order to achieve the optimal accuracy for surface radiation, inf...
