ABI addresses the NWS Imager concerns by: - increasing the spatial resolutions (the NWS goal is 0.5 km for the IR) - improving temporal sampling (faster scanning plus more regions scanned) - adding spectral bands (enables new and/or improved products) A view into the future: simulations of improved cloud, moisture, and surface products with ABI.

Advanced Baseline Sounder on GOES-R *Addresses NWS concerns by improving - temporal resolution: ‘sounding disk’ in 1 hour - vertical resolution 1 km for temp, 2 km for moisture - spatial resolution to 10 km for independent obs * Geo - Interferometer combines several advanced technologies - large focal plane detector arrays - Fourier Transform Spectrometry - on-board data processing. * ABS will provide moisture and cloud information as never before.

Areas within 62 degrees local zenith angle from GOES-East and GOES-West sub- satellite points are indicated. Threshold coverage rate calls for the 62 arc region, excluding half of over-lap, to be scanned each hour. Current GOES -E and -W sounder hourly coverage is also shown.

The advanced sounder has more and sharper weighting functions UW/CIMSS These water vapor weighting functions reflect the radiance sensitivity of the specific channels to a water vapor % change at a specific level (equivalent to dR/dlnq scaled by dlnp).

Summary The satellite remote sensing capability has had many positive consequences: –it has saved thousands of lives and millions of dollars from the ravages of storms; –it has made meteorological satellite data routinely available to nations around the globe; –in conjunction with improvements in numerical weather prediction, it has helped to improve forecast skill significantly; –and as valuable part of GOS it will help discern climate trends. NOAA is investigating the opportunities for further evolving the geostationary and polar orbiting remote sensing capabilities:

Remote sensing of gradients in spectra, space, and time will be better than ever The business of looking down is looking up
