Example Dataset: GOES ABI
Below are some notes on NOAA's GOES satellites, specifically focussing on the Advanced Baseline Imager (ABI).
- Launched on 19 November 2016, operational since 18 December 2017
- Longitude central point: -75.2
- Launched on 1 March 2018, operational from 12 February 2019 to 4 January 2023 at longitude -136.9
- Replaced by GOES-18 due to issues with its Advanced Baseline Imager (ABI) instrument
- Moved to longitude -104.7 (between GOES-16 and GOES-18) and serves as backup for the operational satellites
- Launched on 1 March 2022, operational since 4 January 2023 (replaced GOES-17)
- Longitude central point: -136.9
Earth-facing:
- Advanced Baseline Imager (ABI)
- Geostationary Lightning Mapper (GLM)]
Sun-facing:
- Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS)
- Solar Ultraviolet Imager (SUVI)
Space environment:
- Magnetometer (MAG)
- Space Environment In-Situ Suite (SEISS)
The clear sky mask algorithm uses the GOES ABI visible, near-infrared and infrared bands to automatically assign one of the following 4 classes to each pixel:
- cloudy
- probably cloudy
- probably clear
- clear
ACM data is provided at the native 2km resolution on the ABI fixed grid for full disk, CONUS, and mesoscale coverage regions, at the same temporal resolution as ABI L1b data.
GOES ABI Level 1b and 2 data are named according to the following naming conventions:
<SE>_<DSN>_<PID>_<Obs Start Date & Time>_<Obs End Date & Time>_<Creation Date & Time>.<FE>
where:
- SE = System Environment
- DSN = Data Short Name
- PID = Platform Identifier
- Obs Start Date & Time = Observation Period Start Date & Time
- Obs End Date & Time = Observation Period End Date & Time
- Creation Date & Time = File Creation Date & Time
- FE = File Extension
