Abstract
We have calculated excess path delays (EPD) of microwave due to water vapor in thetroposphere in February and August 1982, using routine radiosonde data on the AerologicalData of Japan. EPD is about 2-3 cm above Hokkaido and northeastern Japan in February, while EPD reaches 28-33 cm on southwestern Japan and the Ryukyu Islands in August.An estimate of EPD by a linear regression model gives standard errors of residuals inFebruary and August as 0.9 and 4 cm, respectively.
