Operating Systems for Snow White
SOWER is currently using the so-called TMAX system.
In this system, Vaisala RS80-15 or RS80-15H radiosonde
is modified and used as the PTU sensors and the transmitter.
interface board processes the data from
Snow White, En-Sci ozonesonde (1Z ECC), and RS80 PTU,
and sends them to the RS80 transmitter.
The ground receiving system consists of
a 400-MHz antenna with an amplifier,
receiver (e.g., icom IC-R8500), modem (Kantronics KAM98), and PC.
An MS-DOS based software
developed by Dr. Holger Voemel is used as the PC software.
