NWP reanalysis data ECMWF (European Centre for Medium-Range Weather Forecasts) ERA-Interim and the new-generation reanalysis data ERA5 provide global grid atmosphere parameters, like surface temperature, different-level pressures, and precipitable water. We show cases of retrieved PWV and validate the precision with radiosonde results and compare new reanalysis dataset ERA5 with ERA-Interim, finding that ERA5 can get higher precision-retrieved atmosphere parameters and PWV. In the end, from our comparison, we find that the retrieved PWV from RO (FY3C and COSMIC) and ECMWF reanalysis data (ERA-Interim and ERA5) have a high positive correlation and that almost all R 2 值超过0.9,比较与无线电探空仪采集,检索,发现无论是RO和ECMWF再分析数据、地面GNSS,或微波卫星,他们都显示小的偏差。SN - 1687 - 725 - 2018/3428303 / 10.1155 x你——https://doi.org/10.1155/2018/3428303——摩根富林明——《传感器PB - Hindawi KW - ER
