EXPERIMENTAL BLIP EVALUATION
Evaluating empirical Tmax adjustments to experimental Walker Ridge BLIP
Questions or problems can be sent to: Dr. John W. (Jack) Glendening
Submitted pilot observations reporting the maximum height of the usable lift (the height of thermal tops or cloudbase) at Walker Ridge will be used to evaluate the accuracy of the experimental Walker Ridge BLIP, which is obtained by empirically adjusting the maximum surface temperature predicted by the MAPS model. The adjustment presently used is simply my guess at a reasonable value - pilot reports will be used to alter that empirical adjustment to give better agreement between predicted and actual heights. At some later time a plot of the predicted vs. observed heights will appear on this page. Some background on the Walker Ridge BLIP and the present BLIPEX page is available here.
At present only the maximum thermal soaring height at Walker Ridge are to be reported. Flights in which you did not reach the thermal top (or cloud base) do not evaluate the BLIP and should not be reported.
To submit your observations, which can be for multiple flights, create an email to be sent to "postmaster@drjack.info" with "BLIPEX" in the Subject line. Your data report will be extracted and machine-processed, so correct formatting is important in the body. The email body should contain one line for each observation, with each line consisting of at least 7 fields, as given below, the fields being separated by at least one space (blank) and with no spaces (blanks) within any field.
The data fields are (their order corresponds to the Javascript form above):
FOR EXAMPLE, to report a "blue thermal" climb to 12300 ftMSL without an average climb rate
blipex= walker MyName 9/31 1300 12300 bt Comments on significant factors
OR, to report a climb to a cloudbase at 12300 ftMSL at an average 400 fpm:
blipex= walker MyName 9/31 1300 12300 cb 400 Comments on significant factors
