PUBLIC INFO. STATEMENT...TECHNICAL IMPLEMENTATION NOTICE 02-30A
NATIONAL WEATHER SERVICE HEADQUARTERS WASHINGTON DC
745 AM PST FRIDAY FEB 17 2006
TO: FAMILY OF SERVICES /FOS/ SUBSCRIBERS...NOAA WEATHER
WIRE SERVICE /NWWS/ SUBSCRIBERS...EMERGENCY MANAGERS
WEATHER INFORMATION NETWORK /EMWIN/ SUBSCRIBERS...
OTHER NATIONAL WEATHER SERVICE /NWS/ CUSTOMERS OF
AVIATION DATA AND FORECASTS...NWS EMPLOYEES
FROM: MIKE CAMPBELL
CHIEF...OBSERVING SERVICES DIVISION
SUBJECT: AUTOMATED SURFACE OBSERVING SYSTEM WIND SENSOR 15
REPLACEMENT
THE FOLLOWING CHANGES HAVE NO DIRECT IMPACT ON NOAA WEATHER WIRE
SERVICE SUBSCRIBERS
THE AUTOMATED SURFACE OBSERVING SYSTEM /ASOS/ PRODUCT IMPROVEMENT
PROGRAM WILL SOON DEPLOY A REPLACEMENT WIND SENSOR. THE NEW SENSOR
WILL REPORT WIND INFORMATION USING THE 3-SECOND WORLD METEOROLOGICAL
ORGANIZATION /WMO/ GUST STANDARD.
THE CURRENT ASOS WIND SENSOR /BELFORT 2000 / USES ROTATING CUPS TO
MEASURE WIND SPEED AND A VANE TO MEASURE WIND DIRECTION. OVER A
2-MINUTE PERIOD...ASOS USES TWENTY-FOUR 5-SECOND AVERAGES TO
DETERMINE THE 2-MINUTE AVERAGE WIND SPEED AND DIRECTION. EVERY
MINUTE ASOS STORES THE HIGHEST 5-SECOND AVERAGE SPEED FOR THE PAST
MINUTE...ALONG WITH ITS DIRECTION...IN THE 12-HOUR ARCHIVE FOR
ADDITIONAL PROCESSING. THIS HIGHEST SPEED VALUE IS USED TO DETERMINE
IF A GUST AND/OR A PEAK WIND REMARK WILL BE REPORTED.
THE NEW ASOS WIND SENSOR /VAISALA 425NWS / IS A SONIC ANEMOMETER. IT
HAS NO MOVING PARTS AND WILL OPERATE BETTER IN WINTER WEATHER
CONDITIONS. AS WITH THE BELFORT SENSOR...OVER A 2-MINUTE
PERIOD...ASOS USES TWENTY-FOUR 5-SECOND AVERAGES TO DETERMINE THE
2-MINUTE AVERAGE WIND SPEED AND DIRECTION. BUT THE HIGHEST 3-SECOND
RUNNING AVERAGE SPEED IS STORED FOR GUST AND PEAK WIND PROCESSING.
WHILE THERE WILL BE LITTLE DIFFERENCE IN 2-MINUTE AVERAGE WIND SPEED
AND DIRECTION REPORTING...THE CHANGES IN GUST AND PEAK WIND
REPORTING MAY BE SIGNIFICANT. WE CAN EXPECT TO SEE MORE GUSTS AND
PEAK WINDS REPORTED WITH THE NEW SENSOR. THE MASS OF THE MOVING
PARTS IN EXISTING SENSORS LIMITS RESPONSIVENESS. THE NEW SENSOR WILL
BE MORE RESPONSIVE TO SHORT TERM GUSTS. THE FOLLOWING ASOS LOCATIONS
HAVE OR WILL TRANSITION TO THE IFW CONFIGURATION ON THE INDICATED
DATES:
SID STATION NAME CONFIGURATION DEPLOYMENT DATE
OKB OCEANSIDE AIRPORT JANUARY 31
CZZ CAMPO FEBRUARY 1
RNM RAMONA FEBRUARY 7
