ORNL DAAC Request for New GCMD Instrument: CO2LAS

Hi,

As we're preparing metadata for data coming out of the ASCENDS Airborne campaign, we find ourselves in need of a new GCMD instrument vocabulary entry, here are the details:

Short name: CO2LAS
Long name: Carbon Dioxide Laser Absorption Spectrometer
Hierarchical Path: Instruments > Earth Remote Sensing Instruments > Active Remote Sensing > Spectrometers/Radiometers > Lidar/Laser Spectrometers > CO2LAS
Description: The JPL Carbon Dioxide Laser Absorption Spectrometer is an aircraft instrument for measuring the integrated column content CO2 beneath an aircraft. It does this using a technique called Differential Absorption in which two, invisible, eye-safe lasers are transmitted from the instrument down to the surface where they are reflected back to the instrument and the power of each measured. One of the lasers is absorbed by carbon dioxide while one is not such that the difference in power received can be used to determine the amount of carbon dioxide in the atmospheric column beneath the aircraft. The instrument has been flown on a Twin Otter DHC-6 aircraft and is being prepared for flight on NASA's DC-8 aircraft.

Please let me know if you have any questions or need additional information.

Thanks,
Yaxing

Thanks Tyler! This looks good. I don't see the path information in the RDF document though.

Best,
