与 ERA5 TCWV、IGRA2 的对比结果在 12 个月处理完后生成于 processed/comparison/（目前为基于 NGL 自带 PWV 的临时对比 provisional）。
Hourly GNSS precipitable water vapour (PWV) for ~119 GNSS stations in Greenland, Iceland and the Canadian Arctic (55–84°N, 80–10°W), derived from Nevada Geodetic Laboratory 5-min zenith total delays, with ERA5-based ZHD (Saastamoinen) and Tm, and comparisons against ERA5 TCWV and IGRA2 radiosonde PW. See METHODS.md.
