MERMAID - Meris Matchup In-Situ Database

MERIS Optical Measurements Protocols

MERMAID provides valuable data for MERIS calibration and validation activities, and therefore it is essential to understand the origin of the in-situ data, the methods by which the measurements were made and the data processing stages. MERMAID consists of datasets from PIs using a variety of measurement systems and following different measurement protocols, including SeaPRISM CIMEL, TACCS, fixed buoys, handheld radiometers and profiling instruments. Two comprehensive documents overviewing MERMAID and describing these in-situ protocols are available: the Apparent Optical Properties protocols, and the Inherent Optical Properties and in-water constituents protocols

Dataset

The following table lists the matchup datasets in MERMAID, the location of the data, the parameters available and the number of matchups. An interactive GoogleEarth map of the locations of all datasets is available to download (you will need to install Google Earth, freely available, to view the dataset locations). Click on a MERMAID site to visit the website/PI’s site at their organisation.
