SURVEY TIVAR-COMMENTS

107 =========== ---------- *AT* Ames, IA
Rare to have local variations due to near uniformity of terrain elevations in region. Sometimes useful in indicating uncertianty.

145 =========== ---------- *AT* Avenal, CA
Haven't used this enough to really evaluate accuracy

166 =========== James Gaar *AT* Ottawa, KS
not tested

179 =========== ---------- *AT* Ellenville, NY near Wurtsboro, NY
This seems like i would be the least useful of all the parameters.

221 =========== Bill Whelan *AT* FDK MD
Rightly or wrongly I use this as a measure of uncertainty in the thermal height and strength f/c. Seems to work fairly well used that way. On a given day and time all thermals seem relatively consistent heightwise and variability over predicts.

261 =========== ---------- *AT* Truckee/Minden
Again local conditions modify the atmospherics to much.

276 =========== Doug Levy *AT* Warner Springs, Ca
I don't use this often

306 =========== ---------- *AT* Mission Peak -- Fremont, CA
I generally use this as an indicator of whether I should look for additional information on the day when Hcrit etc looks poor, but THV is high.

307 =========== ---------- *AT* Elko, BC
I look at this to see if other parameters will be useful.

377 =========== ---------- *AT* Wurtsboro, NY
Difficult to answer Accuracy and Average Error questions.

381 =========== Ben Rogers *AT* hernandez
hard to use. Think I know what's it's for.

441 =========== ---------- *AT* La Grange, GA
Doesn't seem to be worth being bothered about. Maybe THATS why I don't win those contests ... Never checked into the variability of this parameter on different types of days.

467 =========== John Medley *AT* Crystalaire Llano, CA
Have not been keeping track of "error" enough to provide a comment in that column on this one

468 =========== ---------- *AT* Austin, TX
I use this, but not often -- get the info important to me here from a Skew T

511 =========== Steve Bralla *AT* Warner Springs Ca
Sort of understand
