Description
Start Downloading ABI-GOES data from AWS and plot the content.
GOES 16 (also GOES East) is located at 75.2° W and provides most of the U.S. weather information. GOES 17 and 18 (GOES West) are located at 137.2°W over the Pacific Ocean.

ABI_RadF --> Full disk unprocessed
ABI_RadF_Reproc --> "The reprocessed GOES-16 ABI L1b data mitigates systematic data issues (including data gaps and image artifacts) seen in the Operational products, and improves the stability of both the radiometric and geometric calibration over the course of the entire mission life. These data were produced by recomputing the L1b radiance products from input raw L0 data using improved calibration algorithms and look-up tables, derived from data analysis of the NIST-traceable, on-board sources. In addition, the reprocessed data products contain enhancements to the L1b file format, including limb pixels and pixel timestamps, while maintaining compatibility with the operational products."

Problem: After launch, they found its cryocooler did not work properly. This affects the infrared channels some IR data has degraded quality during parts of the day when the sun heats the radiator. Some bands have lower quality in warm seasons.
GOES 18:

New GOES-West satellite launched to fix the GOES-17 cooling issues. Active since mid 2022. Same resolution and channels as GOES-17. No reprocessed data available.

| data | Available Period | notes |
|---|---|---|
| GOES 16 | 2017-2025 | |
| GOES 16 Reproc | 2017-2024 | lower syst unc. |
| GOES 17 | 2018-2023 | IR issues |
| GOES 17 Reproc | 2019-2021 | IR mitigated, but shorter period |
| GOES 18 | 2022-2025 |
Suggestion:
- Download GOES-16 reprocessed
- About the pacific: if we want to have full coverage over the pacific and overlap with Himawari we should also download GOES-17 or GOES-18 (see intro above), but maybe at a later stage?
