ORNL DAAC Request for New GCMD Instrument: AVIRIS-3

[ORNL - yaxingwei]

Hi,

Please help to add a new GCMD instrument keyword.

Short name: AVIRIS-3
Long name: Airborne Visible/Infrared Imaging Spectrometer – 3rd Generation

Hierarchical Path:
Instruments > Earth Remote Sensing Instruments > Passive Remote Sensing > Spectrometers/Radiometers > Imaging Spectrometers/Radiometers > AVIRIS-3

Alternative Labels:
• AVIRIS-3rd Generation

Description: The Airborne Visible/Infrared Imaging Spectrometer – 3rd Generation (AVIRIS-3) is the third of the NASA AVIRIS spectrometer Facility Instrument series. The core spectrometer of AVIRIS-3 is a copy of the optically fast, F/1.8 Dyson imaging spectrometer used by the Earth Surface Mineral Dust Source Investigation (EMIT) onboard the International Space Station (ISS). The AVIRIS-3 uses the EMIT spectrometer design interfaced with a scaled two-mirror telescope enclosed in a compact vacuum vessel to enable measurements from airborne platforms ranging from a Twin Otter to a business jet or a NASA ER-2. AVIRIS-3 is a cryogenic instrument with advanced system control and real-time onboard spectroscopic data processing algorithms evolved from AVIRIS-Next Generation (AVIRIS-NG). The spectral range of AVIRIS-3 is 380 to 2500 nm with 7.4 nm sampling. The radiometric range is from 0 to max terrestrial Lambertian radiance with higher signal-to-noise ratio performance than AVIRIS-Classic or AVIRIS-NG. The spatial field-of-view is 39.5 degrees with 0.56 milliradian sampling. The AVIRIS-3 began operation in 2023. The AVIRIS-3 provides state-of-the-art imaging spectroscopy measurements for NASA science and application in the fields of terrestrial and coastal aquatic plant physiology, surface geology, atmospheric and aerosol studies, environmental science, snow hydrology, volcanology, oceanography, soil and land management, agriculture, limnology, etc.

Thanks Tyler!

Just wanna quickly check with you about the status of the AVIRIS-3 keyword. It will be great to have this keyword available soon, so that a few pieces of our work can move on. Thanks!

Best,

I apologize for the delay as we work through a backlog of keyword requests. Your keyword is scheduled for this week. You can track the progress in this ticket: https://bugs.earthdata.nasa.gov/browse/CMRSCI-4572.
Thank You.
