Atmospheric transmission at microwaves (ATM): an improved model for millimeter/submillimeter applications
- J. Pardo, J. Cernicharo, E. Serabyn
- Physics
- 1 December 2001
We present a model of the longwave atmospheric spectrum that improves in many respects widely used older models such as the microwave propagation model (MPM), since it is based on broadband…
Infrared Space Observatory's Discovery of C4H2, C6H2, and Benzene in CRL 618

The obtained AMSU emissivities are in good agreement with the previously derived SSMI ones, and possible extrapolation of the emissivity from window channels to sounding ones has been successfully tested.
Methylpolyynes and Small Hydrocarbons in CRL 618

- Chemistry
- 10 January 2001
We report on the detection with the Infrared Space Observatory of strong infrared absorption from NH3 and C2H4 in CRL 618. The observed NH3 and C2H4 bands arise from a region with kinetic…
Radiance and Jacobian Intercomparison of Radiative Transfer Models Applied to HIRS and AMSU Channels
The goals of this study are the evaluation of current fast radiative transfer models (RTMs) and line-by-line (LBL) models. The intercomparison focuses on the modeling of 11 representative sounding…
A New Water Vapor Megamaser

- 20 July 2006
We report on the detection of a new megamaser, the 31, 3-22, 0 H2O line (ν0 = 183.310 GHz) in Arp 220, using the Institut de Radioastronomie Millimétrique (IRAM) 30 m telescope. The line is about 350…
Discovery of Interstellar Heavy Water
