Abstract :
A ground based millimeter-wave radiometer has been developed at the Communications Research Laboratory (CRL), Japan. In the spring of 1994 200 and 270 GHz SIS receivers are installed in a transportable cabin with a 60 cm diameter antenna on the roof. The radiometer system will be tested at CRL, Tokyo this year. After tuning the system at CRL it will be moved to suitable sites for upper atmospheric observation in Japan and utilized for operational observation of ClO and other stratospheric and mesospheric constituents. Plans exist to make observations in polar regions
