In order to meet the requirements, documented by the GOES user communities, the instruments designated for the GOES-R notional baseline include an Advanced Baseline Imager (ABI), a Hyperspectral Environmental Suite (HES), a Lightning Mapper, and advanced space and solar observing instruments. These instruments will first be launched in 2012.
The Advanced Baseline Imager is a state of the art, 16-channel imager covering 6 visible to near-IR bands (0.47, 0.64, 0.86, 1.38, 1.61, and 2.26 mm), and 10 infrared (IR) bands (3.90 mm to 13.3 mm). Spatial resolutions are band dependent, 0.5 km at nadir for broadband visible, 1.0 km for near IR and 2.0 km for IR. The ABI will scan the Full Disk (FD) in approximately 5 minutes.
The HES is a multi channel imager and sounder instrument suite with three threshold tasks. HES will provide high-spectral resolution Hemispheric Disk Soundings (DS) and Severe Weather Mesoscale (SW/M) soundings and Coastal Waters (CW) imaging.
HES DS provides 10 km IR resolution from 3.7 mm to 15.4 mm with a one-hour refresh rate of the full disk, 62° local zenith angle. SW/M will cover a 1000 x 1000 km square in 4 minutes, at 4 km resolution for IR. HES CW task will provide at least 14 channels covering 0.4 mm to 1.0 mm, with a 300 m resolution and a 3-hour refresh rate. Coastal Waters are defined as the 400 km zone adjacent to CONUS.
Additional capabilities include an improved Space Environment Monitor, a Solar X-Ray Imager, and direct user services, such as Search and Rescue (SAR), and a Data Collection System (DCS). This paper will focus on the planned instrument capabilities of the GOES-R Series, the space system architecture, and how the new capabilities will complement the future Global Observing System to meet the documented user needs.
