Radiosonde Replacement System (RRS)
Radiosonde Hardware and Workstation
Subsystem (RWS)
Build 2.3 System Test Scheduled for
January to April
2013 Using Test Headers
NWS will conduct
hardware functionality and data communications testing from January through
April 2013 using test headers. As part of the ongoing upgrades to RRS, NWS is
testing a new radiosonde. This testing will require new software to track this
new hardware.
This test will
originate from the NWS Sterling, VA, Field Support Center (SFSC). The test will
consist of daily upper air coded messages transmitted during the asynoptic and normal synoptic times for soundings in a
window from approximately 10Z to 22Z and, as necessary, includes but is not
limited to, when weather conditions and test requirements warrant. These test
messages will be in the same format as operational messages but will have
different data reflecting upper air conditions and coding practices as
explained below.
Two test headers have
been set for the test:
- KSTA test station
id 69990
- KSTB test station
id 69991 for the SFSC.
The KSTA and KSTB
test coded message format will be in the RRS format now in service at 84 upper
air sites. RRS formatted products are a result of changes made to the World
Meteorological Organization (WMO) level selection criteria and updated coding
practices. For additional information regarding these messages, please
reference the manual on codes WMO No. 306, Section A.
When the individual
KSTA and KSTB RRS products are received by the NWS Telecommunications Gateway
(NWSTG), they are packaged with operational upper air products into collective
products converted into BUFR form. These products are then broadcast over
NOAAPORT. The individual collective and BUFR messages are also transmitted from
the NWSTG to NWS users over a variety of communication services. The following
products will be issued during the test:

The format of the
test messages will be the same WMO format for coded upper air messages as used
by the RRS system since 2005. The number of levels in the KSTA and KSTB coded
messages will be similar to the coded messages routinely transmitted from the
operational RRS sites.
