[ABSTRACT]A retrieval algorithm of vertically integrated water vapor amount (precipitable water) over land was applied to the near infrared data of Global Imager onboard Advanced Earth Observing Satellite-II (GLI / ADEOS-II). Comparing the retrieved precipitable water with radiosonde observation, we had some underestimation with some systematic bias for larger water vapor amounts in a preliminary analysis. Accordingly, we re-evaluated a relationship between radiance to be observed with GLI and water vapor amount, carrying out more detailed radiative transfer simulations. The retrieved water vapor amount with the coefficients was compared to radiosonde observation and ground-based microwave radiometer measurements. As a result of the validation, we have a relative error of about 30% and 10%, respectively. It also turns out that the linearity is quite good between the precipitable water with GLI and that with the radiosonde or microwave radiometer observation. Further, it is necessary to compare the satellite-retrieved results with the skyradiometry on a local basis as well as other satellite products on a global basis.
