Recently I‘m using WDQMS to check the availability for the stations in my country.
Could you please answer the following questions？
a) WDQMS shows that the Changsha upper-air station (NWP-ID: 57687) is 'no match in OSCAR/Surface', I want to confirm whether the reason is missing in the observations/measurements for upper-air in OSCAR/Surface?
b) Xi'an upper-air station (NWP-ID: 57036) has been closed. I want to confirm whether changing the declared status to closed then it will not be displayed as a black dot in WDQMS?
c) Shenyang upper-air station (NWP-ID: 54342) was temporarily closed until 2022, now it displayed as black dot in WDQMS. How to modify its declared status?
d) Why are the availability of all upper-air stations in China displayed in orange dots or red dots? Is it because the NWP centres not received humidity for stra (picture 1) or not received all data for stra (picture 2)? The land surface stations should be the issue about reporting interval, we will modify them later.
Looking forward to your reply！
