- Possible options;
- Commercial satellite broadcast;
- Direct broadcast from GOES;
- Internet;
- Dedicated land lines;
- User access from central server;
- Subscription service
- Broadcast subset of data via decommissioned GOES
- Optimal combination of above options;
- Studies to evaluate options ongoing

## GOES Users’ Conference  Recommendations:Data and Product Access: Archive Needs

- Need full spectrum of data from raw data to highly processed products, for applications from the global scale to the mesoscale;
- User friendly
- Easy remote access
- Low cost
- Prompt user access
- Users need metadata
- Browse capability with request submission via Internet

## GOES Users’ Conference  Recommendations...Data Utility: User Education

- Comprehensive education program needed for:
- Forecasters;
- Emergency managers;
- Recreational users;
- Academia;
- Media;
- Industrial users;
- Commercial users

## GOES Users’ Conference I Recommendations: Communication with User Community

- Two way dialogue should continue between GOES User Community and NESDIS via:
- Regular conferences, such as the GOES Users’ Conf.
- Working groups to deal with specific issues;
- Provide a Bulletin Board for information exchange;
- Informational special sessions at end user conferences;
- Provide information via e-mail;
- Make an expert team available to all users and instrument developers;

## GOES Users’ Conference II Recommendations: 

-  Need for 4 km footprint on sounder
- Allows for partial view through thin cirrus
- Provides information in some hurricane eyes
- Provides more information between clouds in convective situations
- Identify clear air turbulence signature

## GOES Users’ Conference II Recommendations: 

- Strong recommendation to explore feasibility of passive microwave instrument in Geo orbit
- Precipitation estimation (real time and climate applications)
- All weather temperature and moisture profiles
- Need a six month program to define pathway to deployment of a Geo microwave instrument

## GOES Users’ Conference II Recommendations: 

-  Data from experimental satellites should be used operationally to prepare for GOES-R
- Develop ways to deal with “firehose of data”
- GIFTS is critical for HES preparation
- Will be over Indian Ocean after 1 year
- Vis channels must be calibration
- Need rigorous on-ground and adequate on-board calibration
- Need cross calibration with other instruments

-  Hyperspectral vis and IR observations preferred       over discrete broad channels
- Benefits include:
- Algorithm transferability
- Channel adaptability
- Application growth
- Inter satellite calibration
- Stable climate record
- Ultimate strength of hyperspectral: simultaneous  and adaptive retrievals of atmos and sfc features.

## GOES Users’ Conference II Recommendations: Climate Issues:

-  Why GOES is important for climate:
- Must understand diurnal and annual cycle
- Recent atm warming is associated with change in the diurnal amplitude of near surface temperatures
- GOES-R will provide better understanding of sfc/ atm processes leading to better climate parameterization
- Geo satellites are only tools capable of resolving the precipitation process at proper space-time scales
- Better climate assessments and forecasts result in large economic benefits

## GOES Users’ Conference II Recommendations: Climate Issues:

-  Calibration is critical for climate applications:
- Must be correlated  with other satellite radiometers
- Cross calibrate with other GOES/ NPOESS/ and international
- Must include all spectral bands
- Must be consistent across the spectrum and over the field-of-regard, before and after launch
- Should be a formal GOES calibration working group
- Calibration info must be included in the data and archive process

## GOES Users’ Conference II Recommendations: Oceanographic Issues:

-  Oceanographic benefits should be in CBA:
- $100M/ year loss to Hawaii due to closure of large swordfish region
- Marine transportation (e.g. fuel savings due to wind and currents)
- Harmful Algal Blooms (e.g. decision to close fisheries and beaches)
- Need ocean color observation
- Observe mesoscale features at hourly intervals and 1 km resolution (greater resolution needed in coastal zone)

## GOES Users’ Conference II Recommendations: Numerical Modeling

-  GOES Sounder vs Polar:
- 6 hr interval OK for global models
- 1 to 1.5 hr needed for mesoscale
- 15 minute desired for severe storms and aviation wx
