Journal ArticleDOI
Multi-angle Imaging SpectroRadiometer (MISR) instrument description and experiment overview
David J. Diner,J.C. Beckert,T.H. Reilly,Carol J. Bruegge,James E. Conel,Ralph A. Kahn,John V. Martonchik,Thomas P. Ackerman,Roger Davies,Siegfried A. W. Gerstl,Howard R. Gordon,Jan-Peter Muller,Ranga B. Myneni,Piers J. Sellers,Bernard Pinty,Michel M. Verstraete +15 more
TL;DR: An overview of the as-built instrument characteristics and the application of MISR to remote sensing of the Earth is provided.
Journal ArticleDOI
Synergistic algorithm for estimating vegetation canopy leaf area index and fraction of absorbed photosynthetically active radiation from MODIS and MISR data
TL;DR: In this article, a synergistic algorithm was proposed to produce global leaf area index and fraction of absorbed photosynthetically active radiation fields from canopy reflectance data measured by MODIS (moderate resolution imaging spectroradiometer) and MISR (multiangle imaging spectraladiometer).
Journal ArticleDOI
Multiangle Imaging Spectroradiometer (MISR) global aerosol optical depth validation based on 2 years of coincident Aerosol Robotic Network (AERONET) observations
Ralph A. Kahn,Barbara J. Gaitley,John V. Martonchik,David J. Diner,K. A. Crean,Brent N. Holben +5 more
TL;DR: In this paper, the performance of the Multiangle Imaging Spectroradiometer (MISR) early post-launch aerosol optical thickness (AOT) retrieval algorithm is assessed quantitatively over land and ocean by comparison with a 2-year measurement record of globally distributed AERONET Sun photometers.
Journal ArticleDOI
Techniques for the retrieval of aerosol properties over land and ocean using multiangle imaging
John V. Martonchik,David J. Diner,Ralph A. Kahn,Thomas P. Ackerman,Michel M. Verstraete,Bernard Pinty,Howard R. Gordon +6 more
TL;DR: Three algorithms are described that will be implemented to retrieve aerosol properties globally using MISR data, and results indicate that aerosol optical depth can be retrieved with an accuracy of 0.05 or 10%, whichever is greater, and some information can be obtained about the aerosol chemical and physical properties.
Journal ArticleDOI
Estimation of vegetation canopy leaf area index and fraction of absorbed photosynthetically active radiation from atmosphere‐corrected MISR data
Yuri Knyazikhin,John V. Martonchik,David J. Diner,Ranga B. Myneni,Michel M. Verstraete,Bernard Pinty,Nadine Gobron +6 more
TL;DR: In this paper, an algorithm for the retrieval of leaf area index (LAI) and fraction of photosynthetically active radiation absorbed by vegetation (FPAR) from atmospherically corrected MISR data is described.
