Have you looked at the other stations that are close by? How "reputable" are these other stations? Are you comparing your readings with lesser calibrated equipment? Or are you one of the better calibrated stations helping to "clean up" a polluted data pool?
An excellent point, because the CWOP 'average' of "...the good, the bad, and the ugly..."
pressures from the surrounding stations has always been suspect
to me. When these surrounding stations are compared to my "reference" sites, some are WAY
off (the ugly), and others (mostly Davis units) are slightly
off (the bad). My "gold-plated" reference sites are: KTUS
(NOAA @ Tucson Airport, 2546'), KDMA
(USAF @ Davis-Monthan AFB, 2703'), and KRYN
(Ryan Airfield, 2417')...and, when I see number consistency like this (small variation) for them, I know they're good:KDMA
, 2703' -- SLP = 985mb, ALT = 997mbKTUS
, 2546' -- SLP = 984mb, ALT = 998mbKRYN
, 2417' -- SLP = 983mb, ALT = 996mb
Sorry for my sophomoric lecture to a Phd candidate. I find that very few people in this forum that are bitchin' about CWOP vs Davis are , in fact, aware of differences. I will also defend myself concerning the "free" statement. I thought it was obvious I was talking about the CWOP service (which is becoming quite spotty, at least for me). Finally, I notice that the high-end weather stations still use serial connections which is the way Davis VP started. Also, I thought the latest Davis consoles had a SLP vs Alt. option, maybe I was wrong.
Oops, first, let me categorically state that I am NOT a trained
weather person (but, I do do my homework
). I am just a retired electronics engineer who, once upon a time long ago, flew as radar operator through typhoons in the Pacific with USN squadron, VW-1, "The Typhoon Trackers" -- hence, the knowledge of aviation weather terms. The Aerographers were the trained 'weather guessers', we (radar electronics) were the 'scope dopes.' My interest in weather stations began when I wanted to know how well (or not) our evaporative cooler was working. Weather is merely a tertiary hobby for me, so I sincerely appologize if I come across otherwise.
"In fact, my concern is centered upon the NOAA / NWS-TUC use and display of "my" weather data" -- I was not aware these people (NOAA / NWS-TUC) used data other than their own.
Don't know about all NOAA/NWS weather sites, but our local NWS-TUC has an "observations" page that simultaneously displays local CWOP/MesoWest/Mesonet/MADIS (but not WU) weather stations as well as their own (KTUS, KDMA, KRYN, etc.) data ( http://www.wrh.noaa.gov/mesowest/gmap.php?map=twc
). The ONLY reason I became involved with CWOP is to provide another citizens' "rain gauge" to help them (NOAA/NWS-KTUS and Tucson water) obtain more/better data on rain amounts and patterns, because the rain amounts reported at the airport do NOT truly represent how much totally
fell nor where
