GOES Program Overview
• GOES satisfies National Weather Service (NWS) requirements for 24
hour observation of weather and Earth’s environment supports stormscale weather forecasting by forecasters and numerical models
• To meet requirements, GOES continuously maintains operational
satellites at two locations (75o West and 135o West), with an on-orbit
space ready in case of failure
On-Orbit Storage

Geostationary Satellites
• Warnings to US Public—detect,

– Hurricanes
– Severe or possibly tornadic storms
– Flash flood producing weather systems
• Imagery for weather forecasting
• Winds for aviation and NWS

• Environmental data collection

– Buoys, rain gauges, etc

Moisture Weighting Functions
High spectral resolution advanced sounder will have more
and sharper weighting functions compared to current GOES
sounder. Retrievals will have better vertical resolution.
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 -- ABS
The Advanced Sounder overcomes existing instrument limitations.
Geostationary interferometer will resolve high temporal and vertical
fluctuations of moisture that are not resolved by current in-situ or
satellite measurements.
Only geostationary interferometer observes critical meteorological
parameters (temperature, moisture, clouds, winds) with necessary
temporal, spatial and vertical resolutions to support future
•
•
•
Nowcasting,
Short-range weather forecasting, and
Longer-range numerical weather prediction.
The Advanced Sounder will provide required high spectral
resolution measurements.
POES Program Overview
• To provide for a continuous flow of global environmental
information in support of NWS operational requirements
• This requires two satellites on-orbit (one in an afternoon orbit and
one in a morning orbit) to ensure continuous coverage during the
time it takes to launch and checkout a replacement satellite

Orbit Period 101 min.

Sun-synchronous Satellites
•
POES (sun-synchronous) satellites provide
continuous global environmental observations
in support of operational requirements for:
– Weather forecasting
– Detection of weather systems and significant
environmental events (i.e., fires, oil spills,
volcanic eruptions)
– Measurements of atmospheric ozone and space
environment
– Collection of data from surface platforms (i.e.,
buoys)
– Search and rescue
•
This requires two satellites on-orbit to ensure
for observations at least every twelve hours
from each point on the Earth
