Sea-Bird Scientific participated alongside 13 organizations from 8 different countries, sending a set of multispectral and hyperspectral radiometers to several locations around the world for laboratory and field validation. For stage 1, dubbed Laboratory Comparison Exercise 1 (or LCE-1), Sea-Bird Scientific sent a set of OCR-200s to several calibration labs around the world for comparison data. Stage 2 (LCE-2) involved sending HyperOCRs and members of Sea-Bird’s Science team to the Estonian Space Research Centre in Tartu, Estonia for field measurements and analysis of sensor uncertainty. Here, scientists suited up in white jumpsuits for laboratory analysis in a dark room, measuring radiance and irradiance.
