GSL HTML5 sounding change details

??-2023

Dated and unnecessary entries were removed from the "Load Soundings" panel (i.e. RAP_130, RAP_OPS_130, RAP, RAP_221, Bak40, Bak13, HRRR, FIM, PROF, RADIO, and isoRR1h. (Removed from the list of data_sources). Routine(s) changed: Welcome.cgi

The data feed for RAOBS has been changed to the prepbufr data, retrieved through the data base. The prepbufr data are more comprehensive, including more stations and levels. Some levels are missing height data, however, and caused problems with labeling on the hodograph. The problem was corrected by testing for missing heights and bypassing the labeling for those levels. Some time lag will be noticed with this change to prepbufr RAOBs, which is due to the processing and delivering of the data. GSL previously ingested raw data through NOAAPORT, and processed the data in-house. Because of the retirement of the people at GSL who maintained this effort, the decision was made to switch to the prepbufr RAOBs. Routine(s) changed:SkewTPlot.java, link for latest_pbraobs.txt added.

13-Dec-2017 (production and beta)

Changes to update the code to be consistent with the latest version of Chrome, by using the latest GWT version (2.8.2). This solved a Chrome problem with the cursor arrow location differing from the location used to display text and parcel trajectories on the SkewT plot. Also, we eliminated the annoying mouse 'hint' ("SkewT Plot") that sometimes appeared when the mouse hovered. Also, cleaned up the Welcome page to eliminate references to Profilers and Radiometeors. Also, added hydrometeor plots as the default on the beta page. Routine(s) changed: SoundingDisplay, sdg.SoundingCanvas, Welcome.cgi, SoundingDisplay.css.

20-Oct-2016 (production and beta)

Changed to work under either 'http' or 'https' protocols. Routine(s) changed: reply-setup.cgi, ParameterGetterSetter, SoundingDisplay, sdg.SoundingLoader, sdg.SoundingDriver.

5-Apr-2016 (production and beta)

Radiometer data from Radiometrics restored. Routine(s) changed: NetCDF.pm installed on the rucsoundings web server (and get_radio.cgi brought up-to-date).

24-Feb-2016 (production)

All beta changes moved to production (with the exception of soundings from the HRRR, due to the load they put on our servers).

23-Feb-2016 (beta)

Fixed a very obscure error that caused the display to hang if users chose both Tephigrams and the 0.5mb display.

19-Feb-2016 (beta)

• Add this parameter to the URL to turn off (nearly) all text and links on the page except for the display itself: &layout=off.
• If you wish to not display each hourly sounding in a time window, you can specify the Number of hours to load as, e.g., 10,3. This will show the soundings in a 10 hour time window, but for every third hour. So, if you want to display GFS soundings every 12 hours for the next 5 days, you'd enter 120,12. Specifying a single number in Number of hours to load will continue to attempt to display a sounding for each hour in the time range.
• The button for the sounding currently displayed is shown with italic text.
• When you overlay multiple soundings (by holding down the shift key as you click additional sounding buttons), the button text changes color to (approximately) match the curves.
• 20 soundings buttons are now shown below the SkewT plot. Previously there were 16 buttons.
• When sending up a parcel trajectory by clicking on the plot, you can specify the dewpoint (as well as temperature and pressure) by holding down the shift key while you click.
• There is a new option for Desired forecast projection called Single-run. If this option is chosen, all soundings within the time window will be taken from the model run having an analysis time specified in the Start date. (This is primarily for model developers. Users interested in the most accurate soundings at each valid time should coutinue to use Desired forecast projection = shortest).
• For the RAP and RAP_OPS_130, we now use the Oprational RAP on the 130 grid, in netcdf format (without hydrometeor information) for speed. Routine(s) changed: wrf_cdf_sdg.c, get_model_directory.pl, get_soundings.cgi.
• (beta site, and GSD computers only). We now allow soundings from the GSD HRRR, but they take many seconds to come up. Asking for too many of these soundings will put an unacceptable load on our server. Routine(s) changed: get_model_directory.pl, get_soundings.cgi.

18-Mar-2014 (production and beta)

• Model names can now be input directly in the calling web page. Also (for the beta) site, soundings from retrospective and other special-purpose model runs are avaliable.
• A bug was fixed involving pre 1970 times causing a crash.
• Code was added to bring up an alert box when uncaught exceptions occur. This is turned off for production use.
• Routine(s) changed: Welcome.html -> Welcome.cgi, SoundingDisplay, ParameterGetterSetter, sdg.LoadPanel.

12-Mar-2014 (production and beta)

We now can optionally show hydrometeors (default for the beta site) for those few models that provide them. Routine(s) changed: SoundingDisplay, ParameterGetterSetter, sdg.SoundingCanvas, sdg.SkewTPlot.

18-Feb-2014 (production and beta)

We now correctly pre-fill the contents of the 'Load Soundings' window including the requested airport, start date, and 'latest' check-box. Routine(s) changed: LoadPanel.

6-Feb-2014 (production and beta)

First production version. Added reading of arguments in the query string. Also, we now only show the debug window if the parameter "&debug=true" is included in the query-string. Also, added a 'Loading' message to indicate when we're waiting for new soundings to be downloaded. Routine(s) changed: SoundingDisplay, ParameterGetterSetter,sdg.SoundingCanvas, sdg.SoundingLoader, sdg.SoundingDriver, sdg.Color.
