Created by Dr. John W. (Jack) Glendening,  Meteorologist  

BLIPMAPs predict thermal soaring conditions resulting from surface heating of the Boundary Layer, by post-processing numerical weather model predictions to provide parameters suited to the needs of soaring pilots.  Users of this viewer are assumed to be familiar with BLIPMAP and its parameters, as described on the CA-NV 21Z BLIPMAP webpage and on the parameter information webpage. 

TO CREATE A BLIPMAP IMAGE SEQUENCE:
(1) Select a day, a time, and a parameter
(2) Single click the "INSERT MAP" button
(3) Repeat for additional day/time/parameter(s)
(4) Single click "FRAME" buttons to move through images

DrJack sez:
Dec 29:  Dallas Gliding Association  has just become an "Angel" and DrJack thanks them for their support.
Dec 22:  Do hawks use BLIPMAPs?  Apparently so, or at least that is one possible interpretation of the findings of Canadian naturalist Paul Summerskill who studied migration routes within the eastern and central continental flyways of North America for the 2003 spring and fall migrations and wrote in his report: "The relationship of [BLIPMAP] Thermal Updraft Velocity to the preferred direction of flight over and adjacent to hawk-watch sites proved to be valuable in locating flights and in predictiong large or small counts."
Dec 3:  Updated the monthly BLIPMAP usage statistics.
Dec 1:  I was away from home for 6 days and the website unexpectedly hit a quota limit.  I'm not sure whether that caused any problems for website users, but it has been fixed now.
Nov 22:  AOL and aggressive anti-spam users:  For those who have forgotten their registration password and asked that it be sent to them via the "User Info Recovery" webpage, I have found that the email sent is being intercepted by some overly agressive anti-spam filters, so you never get it!
Oct 30: Website Operational Again:  Yesterday's problems due to my website provider "upgrading" the website have been fixed and the website is working again.

I only look at the webpages and maps that I use personally or that I suspect might contain an error.  If you notice a consistent problem with either, please let me know.

Heros: Thanks to Vit Hradecky of the Greater Boston Soaring Council for hosting the processing and to John Whitney (F9) for slaying the file-eating dragon inhabiting the original viewer and adding the "ListSAVE/LOAD" feature.  I also want to personally thank those whose support is listed on the Contributors webpage.
