CERRA, the Copernicus European Regional Reanalysis system

Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 763, Page 3385-3411, July 2024 Part B.
A high‐resolution, 5.5 km, regional reanalysis has been produced for a domain covering the whole of Europe from 1984 to 2021 together with a 10‐member ensemble run at 11‐km resolution as well as an offline surface analysis. The reanalyses and re‐forecasts from CERRA show an added value compared to the global reanalyses for almost all variables at the ...

Testing CCC+TL Cosmology with Observed Baryon Acoustic Oscillation Features

The Astrophysical Journal
The primary purpose of this paper is to see how well a recently proposed new model fits (a) the position of the baryon acoustic oscillation (BAO) features observed in the large-scale distribution of galaxies and (b) the angular size measured for the ...

Long Wavelength Measurements of the Cosmic Microwave Background Radiation Spectrum

, 1987
We have measured the temperature of the cosmic microwave background radiation at wavelengths of 0.33, 3.0, 8.2 and 21.3 cm. These measurements represent a continuation of the work reported by Smoot et al. (1985).

Post-inflationary reheating and perturbations of the cosmic microwave background [PDF]

arXiv, 1997
We formulate a gradual dynamical transition from a power-law inflation era with a scalar field to a radiation era with no scalar field including inhomogeneous perturbations to the Friedmann- Robertson-Walker universe. We show that for the cosmic microwave background radiation fluctuations this is excellently approximated by a sudden transition, with ...

Analysis of Polarized Dust Emission Using Data from the First Flight of SPIDER

The Astrophysical Journal
Using data from the first flight of Spider and from the Planck High Frequency Instrument, we probe the properties of polarized emission from interstellar dust in the Spider observing region.

Can X-Ray Jets Be Cosmic Beacons?

, 2001
If X-rays observed from any extragalactic radio jets are due to inverse Compton scattering on the cosmic microwave background (CMB) radiation, then such a source will be detectable with the same surface brightness anywhere in the more distant universe ...

Frequency Channel Selection and Performance Simulation of a Microwave Radiometer for Temperature and Sulfuric Compound Profiling of the Venusian Lower Atmosphere

Earth and Space Science, Volume 11, Issue 6, June 2024.
Abstract Exploring the Venusian lower atmosphere is crucial for studying the atmospheric circulation, surface‐atmosphere interactions, and origin and evolution of the Venusian atmosphere and climate. In this study, we investigate the theoretical capabilities of a downward‐looking passive microwave sounder placed in low Venus orbit to measure the ...

A review of polymer surface modification by cold plasmas toward bulk functionalization

Plasma Processes and Polymers, Volume 21, Issue 5, May 2024.
This article will introduce the concept of plasma‐induced polymer bulk functionalization in the melt state, where cold plasma jets could be applied in reactive extrusion processes to functionalize and facilitate the production of graft copolymers for compatibilization of polymeric blends and fiber composites. A comprehensive literature review on plasma

Interstellar cyanogen and the temperature of the cosmic microwave background radiation

, 1993
We present the results of a recently completed effort to determine the amount of CN rotational excitation in five diffuse interstellar clouds for the purpose of accurately measuring the temperature of the cosmic microwave background radiation (CMBR).
