GOES-R Near-IR Bands
Introduction:
This lesson introduces you to three of the four near-infrared imager bands (at 1.37, 1.6, and 2.2 micrometers) on the GOES R-U ABI (Advanced Baseline Imager), focusing on their spectral characteristics and how they affect what each band observes. For information on the 0.86 micrometer near-IR “veggie” band which is not included here, refer to the Visible and Near-IR Bands lesson.This lesson is a part of the NWS Satellite Foundational GOES-R Course.
Objectives:
- Identify the ABI’s three near-infrared spectral bands (not including the 0.86 “veggie” band) and various phenomena that can be detected in the spectral regions they cover
- Identify which of the near-IR bands is most sensitive to atmospheric absorption and describe the implications for observing clouds and surface features
- Identify sun glint in near-IR imagery
