From: ERA5-SH: A global grided scale height dataset for tropospheric parameters based on ERA5 reanalysis
Variable | Meanings | Unit | Description |
|---|---|---|---|
ZTD | Zenith Total Delay | m | The electromagnetic wave signals experience signal delay in the zenith direction when passing through the troposphere. |
ZHD | Zenith Hydrostatic Delay | m | The signal delay component caused by dry air. |
ZWD | Zenith Wet Delay | m | The signal delay component caused by water vapor. |
WVD | Water Vapor Density | kg/m3 | The mass of water vapor contained in a unit volume of moist air. |
PWV | Precipitable Water Vapor | mm | The total mass of water vapor contained in a unit area air column. |
Tm | Weighted mean temperature | K | The key calculation parameter of the conversion factor from ZWD to PWV. |
