Retrieving of aerosol size distribution based on the measurement of aerosol optical depth

Acta Physica Sinica, 2007
A new method for retrieving aerosol size distribution from measurement of aerosol optical depth is reported. Depending on the rigorous Mie scattering theory and the measured optical depth, dispersing the aerosol size distribution, by using linear-regression method, the aerosol size distribution can be calculated directly.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Variations of Aerosol Optical Depth in Bhaktapur, Nepal

Journal of the Institute of Engineering, 2018
 The study is based on the variations of aerosol optical depth in Bhaktapur, Nepal. Microtops II Sunphotometer, manufactured by solar light inc. USA was used to measure the Aerosol optical depth. The diurnal variations of Aerosol Optical Depth (AOD) in January, 9 at 2.32UT were found to be 1.01, 0.89, 0.81 and 0.61 at 340,440, 500 and 675nm ...

How much of the global aerosol optical depth is found in the boundary layer and free troposphere?

Atmospheric Chemistry and Physics, 2017
. The global aerosol extinction from the CALIOP space lidar was used to compute aerosol optical depth (AOD) over a 9-year period (2007–2015) and partitioned between the boundary layer (BL) and the free troposphere (FT) using BL heights obtained from the ...
