Empirical model for backscattering polarimetric variables in rain at W-band: motivation and implications [PDF]

open access: yesAtmospheric Measurement Techniques
The established relationships between the size, shape, and terminal velocity of raindrops, along with the spheroidal shape approximation (SSA), are commonly employed for calculating radar observables in rain.

Radiometers and Radiometers [PDF]

open access: yesNature, 1876
I HAVE recently been trying some experiments with a radiometer, obtained from Mr. Browning, and as some of my results are different from what I was led to anticipate, I should like to know whether there is anything special in my particular instrument, or whether other people have noticed the same things.

Toward the elimination of bias in satellite retrievals of skin sea surface temperature. 2: Comparison with in situ measurements [PDF]

open access: yes, 1999
We test a new scheme for retrieving skin sea surface temperatures (SSTs) from brightness temperatures observed by the satellite-borne along-track scanning radiometer (ATSR).

HATPRO microwave radiometer measurements at AWIPEV, Ny-Ålesund (2019-2021)

open access: yes, 2022
The microwave radiometer HATPRO has seven K band (22.235-31.4 GHz) channels that are sensitive to the path integrated amount of cloud liquid water (clwvi) and the path integrated amount of water vapor (precipitable water, prw).

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

open access: yesFrontiers 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
