MOONS is a multi-object spectrograph that will be installed at the Nasmyth focus of VLT ESO Telescopes in Chile. The instrument has capacity to deploy approximately 1000 fibers over field view 500 square arcminutes, with total wavelength coverage from 0.6 1.8 μ $$ \mu m, offering both low- and medium-resolution modes. high demand for fast large optics all spectral channels prompted use similar ...

Received ; accepted – 2 – ABSTRACT We estimate the level of confusion of Cosmic Microwave Background (CMB) anisotropy measurements caused by extragalactic infrared sources. CMB anisotropy observations at high resolution and high frequencies are especially sensitive to this foreground. We have combined IRAS data on bright infrared galaxies with information about the Galaxy from the DIRBE and FIR...

The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument, a 10-channel infrared (1.27 16.9 μm) radiometer, was launched on the TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) satellite in December 2001 from Vandenburg Air Force Base. SABER is being used to measure earthlimb emissions and to characterize infrared radiation, allowing calculation o...

Context. The cosmic infrared background (CIRB) consists mainly of the integrated light of distant galaxies. In the far-infrared the current estimates of its surface brightness are based on the measurements of the COBE satellite. Independent confirmation of these results is still needed from other instruments. Aims. In this paper we derive estimates of the far-infrared CIRB using measurements ma...

The Laboratory for Astronomy and Solar Physics ͑LASP͒ continues to conduct a broad program of research and instrument technology development in ultraviolet and infrared astronomy and in optical/UV, X-ray, gamma-ray, and visible-light studies of the Sun. The program encompasses theoretical, observational, and experimental work, using platforms in space such as the Hubble Space Telescope ͑HST͒ Space ...

The Earth Cloud, Aerosol and Radiation Explorer mission (EarthCARE) Multispectral Imager (MSI) is a radiometric instrument designed to provide the imaging of the atmospheric cloud cover and the cloud top surface temperature from a sun-synchronous low Earth orbit. The MSI forms part of a suite of four instruments destined to support the European Space Agency Living Planet mission on-board the Ea...

Radiative fluxes obtained from a numerical model were compared with those obtained from aircraft-based radiometers. Separate comparisons were made for thermal infrared (wavelength X > 2.9g) and solar (2.9g > X > 0.6 g) radiation. The model ignores atmospheric scattering, and assumes that H20, C02, 03 and 02 are the only absorbers. Clouds are assumed to be black bodies in the thermal region, whi...

The character of data required to measure decade-to-century–scale climatic change is distinctly different from that required for weather prediction or for studies of meteorological processes. The data ought to possess the accuracy to detect the small secular climate changes of interest. To be useful to future investigators, the data must include convincing proof that a given level of accuracy w...

Cereal-based and sucrose-coated infant cereals were ground, and the sucrose, glucose, and fructose concentrations were determined with the Agilent Cary 630 Fourier transform mid-infrared, FTIR, instrument and compared to values measured by HPLC. The results indicate that use of the portable FTIR instrument was in line with the HPLC measurements, and that the Cary 630 is suitable for real-time a...
