Calibration Methods The tables below contain lists of documents related to calibration methods for various sensor types. These documents focus on topics such as requirements, guidelines, theoretical studies, or quality control aspects. This list will evolve over time and also be extended to non IVOS sensors. If you feel that documents are missing, please feel free to use the feedback functionality of the CalValPortal to submit your suggestions. Calibration Method Requirements Document Name PDF HTML Author(s) Description Calibration Requirements Consolidation PDF HTML R.Santer et.al. Report on current practices of sensor calibration, covering: (a)Requirements of IVOS calibration (b)Methodology (c)In-Situ measurements and RTC Calibration Requirements Consolidation, annex PDF HTML R.Santer et.al. This short note presents the synthesis of the calibration work, performed between 1996 and 2002, in four distinct measurements campaigns, on the MERIS on-board diffusers and additional Spectralon diffusers dedicated to the calibration of MERIS. Additionally, the results of the ESA study Enhancement of diffusers BRDF Accuracy performedat TNO in 2004-2005 are displayed. Required information on the sensor for running 6S PDF HTML R.Santer This short note describes the pieces of information needed for a given satellite sensor to use 6S. Calibration Method Guidelines Document Name PDF HTML Author(s) Description Retrieval of the aerosol phase function from CIMEL C138 measurements PDF HTML F. Zagolski et al. The objective here is to describe the different steps required to process the CIMEL data in order to derive the aerosol phase function. Introducing the IOP in the 6S code PDF HTML R.Santer et.al. This document describes how to input the aerosol IOPs in the 6S. Theoretical Studies Document Name PDF HTML Author(s) Description Validation Study for standard atmospheric products PDF n.a. R.Santer This report deals with validation activities, namely with regard to standard atmospheric products. Validation Study for land product PDF n.a. R.Santer This report deals with validation activities, namely with regard to land products. Validation Study for ocean colour product PDF n.a. R.Santer This report deals with validation activities, namely with regard to ocean colour. Validation Study for ocean colour product (Annex 1) PDF n.a. R.Santer This report deals with validation activities, namely with regard to ocean colour. Quality Control Document Name PDF HTML Author(s) Description Quality Measurements Definition for ASAR Level 1 Products PDF n.a. ASAR CalVal Team This document describes the procedures to be followed during the C.P. for measuring the ASAR product Uncertainties in the calibration of SPOT sensors with reference to test-sites White Sands and La Crau PDF n.a. R.Santer, C.Schmechtig, K.Thome This paper is focused on the estimation of calibration errors over White Sands and La Crau test sites for SPOT satellite, during their whole life-cycle.
