Atomic and Molecular Data

The HITRAN compilation of the SAO (HIgh resolution TRANmission molecular absorption database) is used for predicting and simulating transmission and emission of light in atmospheres. It is the world-standard database in molecular spectroscopy. The journal article describing it is the most cited reference in the geosciences. There are presently about 5000 HITRAN users world-wide. Applications include NASA Earth observations, the Department of Energy Atmospheric Radiation Measurement program for monitoring climate change, DoD surveillance of aircraft and rockets, and process control in industry.
