Very good agreement shown for irradiance measurements made by novel lightweight Hemispherical Blackbody infrared reference developed in MetEOC projects when compared to reference Tilted Bottom Cavity BB2007 instrument of PMOD/WRC.  Presented as an ePoster on Thursday 25 November 2021 at the the European Space Agency ATMOS-2021 conference, Blackbody Comparison Measurements for Improved Traceability of Longwave Downward Radiation Measurements (ID: 174), by Moritz Feierabend1, Julian Gröbner2, Max Reiniger1, Christian Monte1. —- Understanding climate change starts with understanding the greenhouse effect. This in turn requires knowledge about the infrared radiation that reaches the ground from the atmosphere – the so-called longwave downward radiation. Data on longwave downward radiation is being constantly collected by means of specific infrared detectors found at multiple stations around the globe. To …

The European Union’s Earth Observation program, Copernicus, provides accurate, timely and easily accessible information regarding our planet and its environment. A key component of the program is the Sentinel family of satellites, developed by the European Space Agency (ESA). There are currently five missions in orbit comprising of 8 Sentinel satellites, which have objectives ranging from measuring sea levels to monitoring air pollution. One of these missions is Sentinel-3, (see figure 1), which has a primary focus to monitor the ocean and coastal areas. Currently, there are two Sentinel-3 satellites in orbit, with the first, Sentinel-3A, launched in February 2016 followed by Sentinel-3B in April 2018. A key payload carried by Sentinel-3 is the Ocean and Land Colour Instrument (OLCI), an …
