Planck pre-launch status: calibration of the Low Frequency Instrument flight model radiometers [PDF]

, 2010
The Low Frequency Instrument (LFI) on-board the ESA Planck satellite carries eleven radiometer subsystems, called Radiometer Chain Assemblies (RCAs), each composed of a pair of pseudo-correlation receivers.

Parameters for the depth of the ocean’s productive layer

Frontiers in Marine Science, 2023
Here we compare various parameters that are used to define the depth of the ocean’s productive layer, the euphotic zone, during the initiation of the spring phytoplankton bloom in the North Atlantic (47°N/20°W).

A New Remotely Operated Sensor Platform for Interdisciplinary Observations under Sea Ice

Frontiers in Marine Science, 2017
Observation of the climate and ecosystem of ice covered polar seas is a timely task for the scientific community. The goal is to assess the drastic and imminent changes of the polar sea ice cover induced by climate change. Retreating and thinning sea ice

Design and Analysis of a Next-Generation Wide Field-of-View Earth Radiation Budget Radiometer

Remote Sensing, 2020
Climate on Earth is determined by the Earth Radiation Budget (ERB), which quantifies the incoming and outgoing radiative energy fluxes. The ERB can be monitored by non-scanning wide field-of-view radiometers, or by scanning narrow field-of-view ...
