Subject: Add Simulated Geostationary Operational Environmental

††††††† Satellites Ė R Series (GOES-R) Imagery to the Satellite

†††††††† Broadcast Network (SBN or NOAAPORT) effective

†††††††† May 7, 2015

 

Effective on or after Thursday, May 7, 2015, simulated GOES-R

Advanced Baseline Imager (ABI) imagery will be added to the SBN

and NOAAPORT. The simulated GOES-R ABI imagery is intended only

to test networks and systems. This simulated imagery should not

be used for weather forecasts and analyses.

 

The GOES-R satellite is scheduled to launch in March 2016. NWS

plans call for SBN/NOAAPORT dissemination of a subset of GOES-R

products. To begin testing and evaluation of NWS systems, and to

facilitate testing and evaluation of partner systems, a series

of pre-launch tests is being planned from May 2015 to February 2016.

 

Among the GOES-R products planned for SBN distribution, ABI imagery

is expected to be the most voluminous. The initial focus of

GOES-R-related SBN testing will therefore be on GOES-R imagery.

Simulated GOES-R imagery will gradually be added to the SBN on or

after May 7, 2015. The simulated imagery will be added progressively,

initially restricted to limited data distributions, only within normal

business hours, Monday-Friday, 8 am-5 pm EDT. For the first several

weeks, there will be deliberate pauses in testing. Therefore, further

details about these tests (e.g., specific test segment start and end

times) will be communicated via NOAAPORT Bulletins with message

headersNOUS72 KNCF and ADMNCF.

 

Beginning approximately July 2015, NWS plans to disseminate variable

representative sets of simulated imagery on a quasi-continuous basis

for the duration of these tests. These tests of simulated GOES-R

imagery are expected to extend through 2015, possibly into early 2016.

Simulated GOES-R non-imagery products may also be added to the SBN

during 2015.

†††

The simulated GOES-R imagery will be separated and distinguished from

the SBN's operational traffic in two ways:

 

- The simulated data will be broadcast on distinct channels (PIDs 107

and 108), and thus separated from the SBN's operational data.PID 107

corresponds to the SBNís GOES-R West channel and PID 108 corresponds to

the SBN's GOES-R East channel.

- The simulated data will have WMO Headers (described below) that

are expressly for the simulated imagery, i.e., different from those

of the SBN operational products.

 

The WMO headers have been assigned to distinguish the simulated GOES-R

imagery from other SBN products and to differentiate between GOES spacecraft

stations (i.e., GOES East versus GOES West), geographical sectors

(e.g., Hawaii Regional vs Alaska Regional) and ABI channels, i.e., 1-16.

The headers are as follows, with references to the 11 character template:

 

Template: T1 T2 A1 A2 ii CCCC

 

T1 = T

T2 = I

A1 = R for large-scale (non-mesoscale) sectors

†††= S for mesoscale sectors

A2†† Where A1=R, for large-scale (non-mesoscale) sectors, A2

†††††† corresponds to geographical sectors as follows:

†††= A for the Alaska Regional sector (PID 107)

†††= E for the East CONUS sector (PID 108)

†††= H for the Hawaii Regional sector (PID 107)

†††† = P for the Puerto Rico Regional sector (PID 108)

†††† = S for the East Full Disk (PID 108)

†††† = T for the West Full Disk (PID 107)

†††= W for the West CONUS sector (PID 107)

†††††† Where A1=S, for mesoscale sectors, A2 values corresponds

†††††† to geographical latitude/longitude areas as follows:

†††= A for 45 deg. N <= Lat. < 60 deg. N and

†††††††††††† 120 deg. W < Long. <= 135 deg W

Where mesoscale boxes T, U and Z extend across the prime meridian

(0 deg. longitude) and boxes V and Y extend across the International

Dateline (180 deg. longitude).Sector boundaries of 0 deg. N or 0 deg.

S refer to the equator.The "<=" symbols refer to "less than or equal to."

Mesoscale sectors from GOES West will be disseminated on SBN PID 107 and

mesoscale sectors from GOES East will be disseminated on SBN PID 108.

 

ii = ABI channel number (01 - 16); between the ii and CCCC is

†††††† a space

 

CCCC = KNES (signifies that NESDIS is the creating data

†††††††† center)

Although the WMO header scheme above is for simulated imagery, it is

anticipated that these headers will be applied similarly to the actual

GOES-R imagery products scheduled for SBN addition during 2016.

 

The file format for these products will be netCDF4.

 

Additional information about this new data stream (including headers,

file-format descriptions, sector definitions, sample files and further

test information) will be posted at the following web site during

May 2015, with updates thereafter:

 

http://www.nws.noaa.gov/noaaport/html/noaaport.shtml

 

Again, the simulated GOES-R imagery to be added to the SBN is for system

testing. These products should not be used for weather forecasts or

scientific analyses.
