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 webpageBASIC thermal forecast parameters gives a short list of the parameters most important for thermal soaring.

DrJack sez:   (Latest 5 news items)
May 10, 2012:  RAP replaces RUC:  NCEP has replaced the RUC model with the RAP model.  I am working on making the appropriate BLIPMAP alterations, the primary focus being on needed operational changes - references to RUC in webpages which do not actually affect forecasts will likely remain for awhile.  Operational forecast problems should be reported on the BLIPMAP forum
October 11, 2011:  Continuing BLIPMAPs:  I currently plan to fund and administer BLIPMAPs indefinitely, with all BLIPMAPs remaining freely available to any registered user, but will do little, if any, further development.  To reduce costs to a sustainable level, I am planning to replace my dedicated server with a shared server and do the processing on my personal computer.  Like much else, that switchover has been pending for some time - when it eventually does occur I will alert users via these news items. . Hopefully it will go so smoothly that users will not notice any difference. 
April 1, 2010:  Free BLIPMAPs:  As of today, all BLIPMAPs will be freely available to any registered user.  I currently plan to fund and administer BLIPMAPs through at least September of 2011.  But I will do little, if any, further development.  For quite some time I have been intending to send a situation report to subscribed users, but I find that difficult to write so it has been indefinitely delayed (like much else in my life these days).  I will be changing text on the website which refers to "subscription" use, but that will take awhile. 
Oct 21:  BLIPMAP future:  Options which continue BLIPMAPs without requiring my personal time may emerge - for example, releasing my source code for others to run is a definite possibility.  I will take a six months respite, then see what possibilities have emerged.  While the planned scenario would allow me to terminate BLIPMAPs in October 2010, I would want to continue them (in "free" mode) until such time as alternate runs are available.  But the bottom line is that I must cease my active involvement with BLIPMAPs:  for the past three years, any sitting beyond 2 hours per day has been painful and whereas I was willing to accept some pain for this "labor of love" (hoping the condition was ephemeral, with some diagnosis/solution eventually being found!), I am no longer willing to program in pain and cannot spend the computer-sitting time necessary to maintain the site.

All BLIPMAPs are freely available to registered users.  Registration (free) is needed for direct (no-nag-screen) forecast access.  New users can Register here.  Currently registered users can Logon (get new cookie) here or view registration (cookie) status here.  More info is available at the Registration Information webpage. 
There are many advantages to having one person's knowledge be shared and available to others, so I expect most BLIPMAP issues to be handled through the DrJack Forum and ask those who have a question or problem or experience which could be of interest to others to post it there.  This allows others to comment on the matter if they have any personal experience and also allows any response I make to be read by others.  If you send me an email, I will respond personally only if it's nature is not appropriate for such posting - in other cases I will simply reply with a request to post to the forum. 
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 post a message on the DrJack Forum.

Medal Heros: Thanks 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.
