The moon is a very stable reference source that has been used for the space-borne sensors’ radiometric calibration and/or radiometric stability monitoring. In this paper, we present an approach that uses the sensors’ on-orbit lunar observations for their spatial characterization and apply the method to the MODIS instruments that are currently operating on board NASA EOS Terra and Aqua satellites. Both MODIS instruments perform monthly lunar observations. The spatial characterization results derived from the lunar observations using this algorithm are compared with those obtained from the MODIS Spectro-Radiometric Calibration Assembly (SRCA), which is an on-board calibrator capable of performing spatial characterizations for all MODIS spectral bands. The new approach can be applied to other remote sensing instruments.read more

Uncertainties in Coastal Ocean Color Products: Impacts of Spatial Sampling
TL;DR: Simulation of MODIS and VIIRS OC products from 30m resolution OC products derived from the Operational Land Imager (OLI) aboard Landsat-8, to examine impacts of spatial sampling on both cross-sensor product intercomparisons and in-situ validations of Rrs products in coastal waters concludes that expected biases induced by the spatial sampling in product inter comparisons are mitigated when products are averaged over at least 7km×7km windows.

Use of the Moon for Calibration and Characterization of MODIS, SeaWiFS, and VIRS
TL;DR: The need for long term global data sets to enable quantitative studies of changes in the Earth's climate leads directly to a requirement for a radiometric calibration source that is stable over several decades (and possibly several centuries) to levels of better than one part in a thousand, that can be readily used on-orbit and that is suitable for inter-comparison of a wide variety of imagng radiometers as discussed by the authors.
