           DEPLOYMENT OF THE ALTERSHIELD FOR THE ALL
           WEATHER PRECIPITATION ACCUMULATON GUAGE /AWPAG/

NOTE:      THE FOLLOWING CHANGES HAVE NO DIRECT IMPACT ON
           NOAA WEATHER WIRE SERVICE SUBSCRIBERS.

NWS IS DEPLOYING AN IMPROVED ALTERSHIELD/WIND SCREEN FOR
THE ASOS AWPAG. THE ALTERSHIELD HAS BEEN TESTED AND SHOWN
TO IMPROVE PRECIPITATION ACCUMULATION CATCH ACCURACY DURING
WIND DRIVEN SNOW EVENTS.

A COMPARISON STUDY WAS CONDUCTED TO EVALUATE SENSOR
PERFORMANCE CHANGES THAT MIGHT OCCUR DUE TO THE
IMPLEMENTATION OF THE ALTERSHIELD. THE RESULTS OF THE STUDY
SHOWED IMPROVED PRECIPITATION CATCHES DURING WIND DRIVEN
SNOW EVENTS. COMPARISON EVALUATION STUDIES AND THEIR
RESULTS ARE AVAILABLE AT /USE LOWERCASE/:

HTTP://WWW.WEATHER.GOV/OPS2/SURFACE/ASOSIMPLEMENTATION.HTM

THE IMPROVED ALTERSHIELD DESIGN CONSISTS OF AN 8 FOOT
DIAMETER WIND SHIELD THAT WILL BE DEPLOYED AT UP TO
316 ASOS EQUIPPED AWPAG LOCATIONS. HOWEVER AT UP TO
16 AWPAG LOCATIONS... BECAUSE OF SPACE LIMITATIONS... A
SMALLER 6 FOOT DIAMETER SHIELD WILL BE INSTALLED. THE NEW
ALTERSHIELD WILL BE USED TO SUPPORT ASOS OPERATIONS
BEGINNING WITH INSTALLATION. A LIST OF SITES EQUIPPED WITH
EITHER THE 8 FOOT OR 6 FOOT ALTHERSHIELD AND INSTALLATION
DATES MAY BE FOUND AT THE FOLLOWING URL:

PRECIPITATION ACCUMULATION INFORMATION IN ANY OF THE ASOS
PRODUCTS OR MESSAGES.
