Modifications in the July release of the fxa-3.0 build
These are changes from the original (February release) fxa-3.0
software build.
(Those marked 3.01 were not in the NWS release, but are
in the 13 May Denver installation. Subsequent changes, not yet
installed in Denver, are marked 3.01 (no italics). Sorry for
the confusion.)
Infrastructure
- The system was upgraded from HP/UX v10.10 to v10.20. This includes
a change from VUE to CDE workspace managers. The login procedure is
slightly different, and the front panel (the D2D, E2D, etc. button
bar) has changed, but the startup procedure is still the same. (On the
up side, the front panel now properly displays both local and UTC
clocks.)
- PRC supplied a new version of the SBN CP software (using an
upgrade to the operating system, HP-RT 2.2 and DWB v7). The WFO-A data
acquisition software was modified to accommodate these changes.
- Also new in the acquisition software is a time-out mechanism that
will send a message to the NCF if no data are received on either the
TG or NESDIS circuits.
- The data and process monitors are now part of the software build,
rather than being stand-alone systems. They, too, include AWIPS
monitor and control hooks to alert NCF to problems.
- Data availability is improved by making several decoders more
reliable.
- 3.01 The radar subsystem has been certified by the
OSF. Numerous changes have been made in the radar interface to make
the system more stable.
Text workstation
New features
Improvements
- Pilot reports are now handled similarly to the AFOS method, stored
by state. Routine reports are stored as PRCxx and urgent reports as
PIRxx.
- 3.01 The zones/Nowcast formatter programs have been
improved to more rigorously check the format of the input work files.
Also, the message window for these has been enlarged so error messages
can be read easily by the user.
- 3.01 Inventory times in the browser now auto-update.
- 3.01 Scripts can now be renamed, via an option under the
File menu of the script editor. Also, a new script no longer carries a
default name. When you save a new script, you're prompted for a name
under which to save it.
Bug fixes
- 3.01 A:HH CCCNNN commands can be entered again, as it's
possible to enter a space into a product request. (This request still
does not work properly, though.)
- 3.01 The behavior of the browser inventory process has
changed. Previously, if you selected, say, MTR, then another NNN, you
had to wait perhaps quite some time for the MTR inventory to display
before the browser would show the new NNN's XXXs. Now, the latter will
come up right away (though its inventory will still wait until the
first inventory completes). The result is a much more responsive
browser.
- 3.01 When you are viewing the earliest version of a product
and select Previous, the screen no longer clears.
- 3.01 A bug that caused the alarm bell sometimes to stay
around even when all alarm products had been dealt with has been
fixed.
New or remaining bugs
- The WarnGen window occasionally doesn't pop up automatically,
because the text notification server has crashed or wasn't
started). Workaround: Request DENWRKWGx from any window. (The warning
expiration reminder won't work in this case.)
- The text subsystem still uses 3-character station IDs. As a
result, the Help function in the browser and the button-2 popup
station ID info on METAR messages have some problems. In the former,
the trailing three characters are used (assuming a K), and some
lower-48 sites are identified as Alaskan, and vice versa. In the
latter, only Kxxx sites read 4 characters. Others read just the first
3, so Pxxx IDs are not found or are incorrect.
- Torn-away menus don't respond to changes in the edit state.
- The text database now distinguishes products by length. Short
products (those less than 2000 bytes) are not vulnerable to the text
database corruptions that have been an occasional problem. "Long"
products must be defined as such; if a product exceeds the limit, but
is not specified on the list of long categories, it will be truncated.
Please inform FSL if you find any that are truncated so that they can
be added to the list of long products.
- The text browser does not show all categories that are available
for other sites. In general, all products appropriate for the U.S. are
stored in the text database, so even though the text browser doesn't
include them, they are there. An example is zone forecasts for many
areas.
- A:HH CCCNNN does not work properly. A: does.
- When the Nowcast generator detects a format error, it creates and
stores a blank (header-only) product.
Graphic workstation
New features
- 3.01 If an IGC (display process) crashes, it will restart
automatically. This eliminates occurrences of a black, unusable,
monitor pane, and should greatly reduce the number of restarts
required. If a restart occurs, you'll get a red-box message so
indicating.
- 3.01 Hydro applications are now available from the D2D menu,
rather than from the root pop-up/other workspace.
Improvements
- The "every image" choices for satellite are now on the bottom half
of the first-level satellite menu, instead of in a submenu.
- When you set the Volume Browser to Animate in Space, the Prognosis
loop load mode is automatically selected. Previously, this mode
"stuck" until you changed the Volume Browser back to Animate in Time.
If the VB was closed or hidden, or simply unused, it was not at all
obvious why you couldn't select a different load mode. Now, selecting
a different load mode forces the Volume Browser to switch to Animate
in Time mode.
- 3.01 Several items have been added to the skew-T
plots. These include helicity, storm motion, and storm info on the
hodograph; and helicity, storm motion, height of wet-bulb zero,
soaring parameters (trigger temp and soaring index), CCL, LCL, LFC,
and convective gust potential in the annotation text. Also, the text
below the plots will abbreviate when character size gets large to
allow you to see as many of the numbers as possible.
- 3.01 A few changes have been made to the radar
menus to make them easier to understand and more consistent with the
RPS and one-time-request applications.
- 3.01 Several additional fields are now available
from the MRF. These include data at 1000, 850, 700, 300, and 250 hPa,
convective precip, and wave-5 height. Also, the Northern Hemisphere
and North American grid sets for MRF are now equivalent.
- 3.01 Numerous additional AVN model fields are now
available on the double-resolution grid. This will improve their
displayed appearance. Vertical velocity levels now also include 900,
950, and 1000 hPa.
Bug fixes
- Zooming in on a skew-T plot is now safe. The bug that caused the
display to lock if the chart moved off the top of the display is fixed.
- Previously, the display might crash while loading a text-based
product (e.g., flash flood guidance, SELS watch), or the product might
display improperly. This has been fixed.
- Flash flood products display again. (These worked prior to the
February upgrade.)
- All weather symbols (SQ, at least, used to be wrong) now are
correctly positioned on METAR plots.
- Some radar products cannot be handled by the current software.
These have been removed from the OTR and RPS list application menus,
and from the display menus. (OK, this is not quite a bug fix, but a
worthwhile work-around.)
3.01 Weak Echo Region, Hourly Digital Precip Array, Radar Coded
Message (unedited), and Combined Moment are re-added to the OTR list.
- Previously, some METAR obs didn't get plotted despite the fact
that data for those sites was in the text database - we believe that
this is fixed.
- Layer reflectivity and echo tops images can be displayed.
- In the one-time request (OTR) application, you no longer can request
more than one version of a product from a dial-out radar.
- There was a problem with grid cross section problems that manifested
itself in at least two ways: sometimes displaying such cross sections
would hang the workstation; and at least one user had problems with a
continual reload scenario when calling a cross section from a procedure.
This was traced to an over-notification of grid arrivals, and has been
fixed.
- When you Exit the display software, the Volume Browser (and any
other open applications) now shuts down, too.
- A full complement of satellite images is available in the Every
Image section of the satellite menu (active on NH, NA, and CONUS
scales). Previously, you often would find only one (sometimes zero)
versions there.
- 3.01 Mapping of storm track and mesocyclone radar graphics
was incorrect. It's now fixed.
- 3.01 A fix was made to the SPC ("SELS") watch display. In
certain cases, one of the vertices was incorrectly plotted off screen,
resulting in a rather bizarre box.
- 3.01 There was a problem with a few infrequently-used grid
products (items involving adding two fields together - e.g., MAPS
precip). This has been fixed.
- 3.01 METAR precip plots are now correct. Previously, they
often plotted amounts too high, due to an error in interpreting the
precip code in the obs.
- 3.01 ALERT precip plots are now properly scaled, and are
summed from all 5-minute reports. (This was fixed with a patch on 1
August.)
Remaining bugs
- The default load mode (Valid Time Sequence or Latest Model Run) is
not restored after a swap.
- Graphics controls are not properly set with bundle loads. Although
the magnification and density are set as they should be, the graphics
controls dialog box does not change to reflect the current settings.
- When you load products, clear, then swap the now-empty frame into
a small pane, it improperly shows the time label from the previously
displayed product.
- "Novocaine" - Occasionally the workstation will not respond to any
mouse inputs. These episodes typically last around 5 seconds.
- LDAD plots - We still are lacking complete metadata on the CDoT
stations, so there are a some stations we can't plot.
- National-scale satellite images do not auto-update. (The entries on
the "Every Image" part of the menu do.)
- 4-panel charts don't print correctly. Only one panel prints, though
all four labels are included.
- Once you're in 4-panel mode, you stay there until explicitly
Clearing the screen. If you select products on a different
scale, you'll get the same thing loaded in each panel.
- LAPS surface moisture convergence has the wrong sign.
- The Northern Hemisphere and North American "Every Image" menus,
though up to date, often yield zero or one image.
- Some radar products display incorrectly, including Composite
Reflectivity Contour and Severe Weather Analysis (window) products.
New bugs
- In the Product Maker, the scalar load button does not work.
- SRM cursor read-out in range-folded areas reads ">50 kts".
