The Collection 6 MODIS aerosol products over land and ocean
Robert C. Levy,Shana Mattoo,L. A. Munchak,Lorraine A. Remer,Andrew M. Sayer,Andrew M. Sayer,Falguni Patadia,Falguni Patadia,N. C. Hsu +8 more
TL;DR: The Collection 6 (C6) algorithm as mentioned in this paper was proposed to retrieve aerosol optical depth (AOD) and aerosol size parameters from MODIS-observed spectral reflectance.
Journal ArticleDOI
MODIS Collection 6 aerosol products: Comparison between Aqua's e-Deep Blue, Dark Target, and "merged" data sets, and usage recommendations
Andrew M. Sayer,Andrew M. Sayer,L. A. Munchak,N. C. Hsu,Robert C. Levy,Corey Bettenhausen,Myeong-Jae Jeong +6 more
TL;DR: In this paper, the authors compare the performance of the Enhanced Deep Blue (DB) and Dark Target (DT) algorithms over land, and a DT over-water algorithm over desert/urban areas.
Journal ArticleDOI
MODIS 3 km aerosol product: algorithm and global perspective
TL;DR: In this article, the MODIS aerosol team released a nominal 3 km product as part of their Collection 6 release, which is able to retrieve over the ocean closer to islands and coastlines, and is better able to resolve fine aerosol features such as smoke plumes over both ocean and land.
Journal ArticleDOI
MODIS 3 km aerosol product: applications over land in an urban/suburban region
L. A. Munchak,Robert C. Levy,Shana Mattoo,Lorraine A. Remer,Brent N. Holben,Joel Schafer,Chris A. Hostetler,Richard Ferrare +7 more
TL;DR: In this article, the authors evaluate the 3 km product over the Baltimore-Washington D.C., USA, corridor during the summer of 2011 by comparing with spatially dense aerosol data measured by airborne High Spectral Resolution Lidar (HSRL) and a network of 44 sun photometers (SP) spaced approximately 10 km apart, collected as part of the DISCOVER-AQ field campaign.
Journal ArticleDOI
A surface reflectance scheme for retrieving aerosol optical depth over urbansurfaces in MODIS Dark Target retrieval algorithm
TL;DR: In this paper, the authors address the inaccuracies produced by the MODIS Dark Target (MDT) algorithm aerosol optical depth (AOD) retrievals over urban areas and suggest improvements by modifying the surface reflectance scheme in the algorithm.
