An understanding of the surface albedo of high latitudes is crucial for climate change studies. MODIS albedo retrievals flagged as high quality compare well with in situ Greenland Climate Network (GC-Net) measurements but cover too small an area to fully characterize Greenland's albedo in non-summer months. In contrast, poor quality MODIS retrievals provide adequate spatio-temporal coverage, bu...

This study aims to evaluate the performance of long-term Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) Collection 6.1 (C6.1) in determining spatiotemporal variation aerosol optical depth (AOD) and types over Indonesia. For this purpose, monthly MODIS DB AOD datasets are directly compared with Aerosol Robotic Network (AERONET) Version 3 Level 2.0 (cloud-screened qual...

With the increasing interest for Arctic Ocean resources and faced with its sensitivity to climate change, it is important to accurately monitor the chlorophyll-a (Chla) concentration that is a key indicator of phytoplankton biomass and marine productivity. The performances of three operational algorithms (OC4v6, OC3Mv6, OC4Mev6), two Arctic adapted algorithms (OC4L, OC4P), and one semi-analytic...

if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...

The Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) has been widely used in atmospheric environment and climate change research. Based on data of the Aerosol Robotic Network Sun–Sky Radiometer Observation Yangtze River Delta, retrieval accuracies MODIS C6.1 Dark Target (DT), Deep Blue (DB), C6.0 Multi-angle Implementation Atmospheric Correction (MAIAC) products...

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board the NASA Terra satellite has been collecting global data since March 2000 and the one on the Aqua satellite since June 2002. In this paper, cirrus cloud properties derived from ground-based remote sensing data are compared with similar cloud properties derived from MODIS data on Terra. To improve the space–time correlation betwe...
