Are there barographs available which plot the first derivative of the pressure
with respect to time, and would such a plot be useful alongside the pressure
signal itself?
I have developed a barograph which is is capable of such things, but I wonder
what the most useful printout might be. The current state of the art is
visible at http://www.meteormetrics.com and I would welcome comment,
especially if there is a useful parameter I could calculate and include on
future versions.
Thanks

I would argue that it would be very useful... if the information could
be distributed to the forecasters as part of the site's observation. It
should permit better automated analysis of frontal passages (trough
passage), Low deepenings/weakenings, etc.... stuff much of which is
either done manually or by software kludges interpolating from the
hourly MSLP values. As long as the primary curve is suitable smoothed
(running time-average over several minutes, perhaps??) before the
derivative is taken.
By the way... what is the pressure-sensing technology on that device?
It surprises me that it would not be considered accurate to a tenth of
mb, given all the temperature compensation, etc. ???
