ORNL DAAC Request for Revising an Existing GCMD Project: AVIRIS

Hi,

We'd like to request another revision to the definition of the AVIRIS project keyword. This revision contains improvements to clarify a few minor details.

UUID: d6b1012f-7e03-44cc-96f7-1f580c5eaad1
Short name: AVIRIS

New Definition: The Airborne Visible InfraRed Imaging Spectrometer - Classic (AVIRIS-C), Next Generation (AVIRIS-NG), and 3rd Generation (AVIRIS-3) are three Facility Instruments (FIs) that are part of NASA’s Airborne Science Program (ASP) and the Jet Propulsion Laboratory’s (JPL) Earth Science Airborne Program. The AVIRIS-C is an imaging spectrometer that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral channels with wavelengths from 400 to 2500 nanometers (nm). The AVIRIS-NG is the successor to AVIRIS-Classic and provides high signal-to-noise ratio imaging spectroscopy measurements in 425 contiguous spectral channels with wavelengths in the solar reflected spectral range (380-2510 nm) with 5 nm sampling. The AVIRIS-NG started operation in 2014 and is expected to replace the AVIRIS-C instrument. The AVIRIS-3 is the third of the AVIRIS spectrometer FI series and has higher signal-to-noise ratio performance than AVIRIS-C or AVIRIS-NG. The core spectrometer of AVIRIS-3 is an optically fast, F/1.8 Dyson imaging spectrometer spanning a wide width (39.5-degree field of view). The AVIRIS-3 provides measurements in 285 contiguous spectral channels with wavelengths in the solar reflected spectral range (390-2500 nm) with 7.4 nm sampling. The AVIRIS-3 started operation in 2023. Data from AVIRIS-C, AVIRIS-NG, and AVIRIS-3 are applicable to a wide range of studies in the fields of terrestrial and coastal aquatic plant physiology, atmospheric and aerosol studies, environmental science, snow hydrology, geology, volcanology, oceanography, soil and land management, agriculture, and limnology.

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

Thanks,
Yaxing

@ORNL - yaxingwei This appears to be a duplicate request. The project keyword was already updated. Please review https://gcmd.earthdata.nasa.gov/KeywordViewer/scheme/all/d6b1012f-7e03-44cc-96f7-1f580c5eaad1?gtm_keyword=AVIRIS&gtm_scheme=projects and let me know if any additional changes are needed. Thank You.

Hi @GCMD - tstevens ,

Apologies for the confusion. But this is a new revision request, different from from the one we submitted back in June.

FYI, for this new revision request, due to some glitch in ED Forum, the same request was submitted multiple times a few days ago. Those duplicated requests have been deleted. But again, this new request (and the duplicated requests) is different from the one we submitted in June.

Hope this clarifies things a bit. Let me know if you have any questions.

Thanks,
Yaxing
