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.

April 16, 2024:  NWS data file problem:  Download of the National Weather Service datafiles used for input data is now failing for both NAM and RAP, so no model updates.  Am looking into problem, don't know now whether another suitable file can be found.
April 17, 2024 update:  Has been major outage at NCEP center, dunno problem but they've sent out an 'all hands on deck' message as they try to recover.
April 18, 2024 update:  Have switched to alternate source for datafiles, appears to be working.

April 15, 2024:  Server Costs: 
    Yearly Expenses:  website ~$600 + registration ~$100 = $700 / year
    Yearly Income:  2023: $539

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 Blipmap 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 Blipmap Forum.
