Journal ArticleDOI
The MODIS Aerosol Algorithm, Products and Validation
Lorraine A. Remer,Yoram J. Kaufman,Didier Tanré,Shana Mattoo,D. A. Chu,J. V. Martins,Rong-Rong Li,Charles Ichoku,Robert C. Levy,Richard G. Kleidman,Thomas F. Eck,Eric Vermote,Brent N. Holben +12 more
TL;DR: In this article, the spectral optical thickness and effective radius of the aerosol over the ocean were validated by comparison with two years of Aerosol Robotic Network (AERONET) data.
Journal ArticleDOI
Validation of MODIS aerosol optical depth retrieval over land
TL;DR: In this article, the first time over land in the visible wavelengths by MODIS (Moderate Resolution Imaging Spectroradiometer) onboard the EOSTerra spacecraft, the authors derived the aerosol optical depths from more than 30 AERONET (Aerosol Robotic Network) sites globally.
Journal ArticleDOI
Global monitoring of air pollution over land from the Earth Observing System‐Terra Moderate Resolution Imaging Spectroradiometer (MODIS)
D. A. Chu,Yoram J. Kaufman,Giuseppe Zibordi,Jiun-Dar Chern,Jietai Mao,Chengcai Li,Brent N. Holben +6 more
TL;DR: In this article, the results of applying MODIS-derived aerosol optical depths (T a ) to regional and local air pollution in terms of accuracy (ΔT a = ±0.05 ± 0.2τ a ) and spatial sensitivity of the retrievals.
Journal ArticleDOI
Validation of MODIS aerosol retrieval over ocean
Lorraine A. Remer,Didier Tanré,Yoram J. Kaufman,Charles Ichoku,Shana Mattoo,Robert C. Levy,D. A. Chu,Brent N. Holben,Oleg Dubovik,Alexander Smirnov,J. V. Martins,Rong-Rong Li,Ziauddin Ahmad +12 more
TL;DR: In this article, a two-month data set of MODIS retrievals co-located with observations from the AErosol RObotic NETwork (AERONET) ground-based sunphotometer network provides the necessary validation.
Journal ArticleDOI
Retrieval, validation, and application of the 1-km aerosol optical depth from MODIS measurements over Hong Kong
TL;DR: The MODIS algorithm is modified to retrieve aerosol optical depth (AOD) at 1-km resolution over Hong Kong, a city of just over 1000 km/sup 2/ with very complex surface features, suggesting that the new 1- km AOD data can be used to better characterize the particulate matter distribution for cities like Hong Kong than the MODIS standard products.
