96: REMINDERS, Site Steamboat, Tue 20-Feb-2001 19:02:21 GMT, Notes for system changes/upgrades
Using this entry to list things which could be improved. Most are minor.

When RASS begins, ramp the volume over 3-seconds (Charlie has this on his list).

GLASS realtime software: for one sounding the 10-second data was just plain wrong. Altitude got stuck at 2225m. Pressure and all else in the RAW data looked ok.

GLASS realtime software. The U and V of the RAW data have the wrong sign (U and V are positive with flow towards the East and North). The 10-second data, including direction, were correct. The Zeb display was also correct. Ned notes that it is Vaisala who uses the (wrong) convention of U,V being FROM East,North.

GLASS software: The realtime T display doesn't show temperatures below -50C, so we can't locate the tropopause height. This would be useful information in realtime for some projects.

MAPR PC hung. Noted because the clock stopped, other pc could not access contour plot web page. Before crash it was running windrasstms, doing a backup tape, and running Bill's plot_latest_sounding.csh. (did this twice now).

On Bill's sounding plots it would be nice to have wind speed and direction in addition to the U,V which are there.

Zeb radiation plot: The axis labels are good, but the legend labels are misleading.

On all plots of sounding data, when is RH from saturation with respect to water and when with respect to ice?

MAPR: We need a RASS temperature display (web or zeb)

MAPR: could use a raw voltage output for the scope to examine clutter, etc.
(Mike says this must be done by Charlie after the signal is digitized and
mixed to baseband.).

GLASS: During the initialization, is the surface met that I accept used as the
grounding point for the data? If so, it can be a long time (15 min or more)
from the actual launch time. [Mike says that is the data used; so could a
way to update this be added?].

General: Get a triple-piont table for trailer. Surface met says the
temperature is about -2 C, but the ice is melting. Is it because of the lowe
than STP standard pressure or because of salt or other contaminants?

Also, get an ice crystal habit diagram for trailer..

MAPR real-time display: power spectra sign convention is reversed (display only)
It seems downward are negative values (left of zero), but DBS displays show it
to be positive (right of zero). DBS displays the "radial velocity" with the
convention that it is positive towards the radar (down).

Zeb raingauge display: It is labeled as mm and each trip appears to be 0.1 mm.
But Bill said each trip is actually 0.1 inch?
