The Pico Balloon experiments are fascinating from several perspectives
Well done Andy!
This site may be of interest in predicting the direction of travel of
the payload at any given time.
A menu is available when you click on "earth" at the LH side of the
screen. You can check the flow at various levels by clicking on the
various hPa items on offer. I once did a translation from these
options to the corresponding flight levels (altitude values) but I've
misplaced the envelope somewhere. There are lot of options on this
page, and as a person who has worked with the weather for most of my
life and also in my sport, it's a very interesting presentation. Zoom
in /out, drag the earth to any place you want to see - Fascinating!
Looking at the most recent payload when it was drifting NE from the
greater Sydney area a day or so back, I was almost prepared to predict
then that it might wind up traveling over the central North Island of
New Zealand on the basis of the 700 hPa flow, but I wasn't game to stand
up and say so.
