GOES-R Visible and Near-IR Bands
Introduction:
This lesson introduces you to the two visible and one of the near-infrared imager bands on the GOES R-U ABI (Advanced Baseline Imager), focusing on their spectral characteristics and how they affect what each band observes. Also included is a brief discussion of the customization of visible enhancements as an important consideration for improving the depiction of various features of interest.This lesson is a part of the NWS Satellite Foundational GOES-R Course.
Objectives:
- Identify the ABI’s two visible spectral bands, the “blue” and “red” bands, and various phenomena that can be detected in the spectral regions they cover
- Identify one of the ABI’s four near-IR spectral bands, also known as the “veggie” band, and describe how it contrasts to the two visible spectral bands
- Identify sun glint in visible and near-IR imagery
- Identify favored times for viewing haze, dust and smoke, and which of the visible and near-IR bands is generally more sensitive to atmospheric aerosol detection
- Briefly state the advantage of adjusting enhancement tables in visible imagery for feature identification
