You can't change elevation. It used to be something that you could enter. With the new WU it is automatically determined when you create a station. If you want to test you don't need to delete your old station ID. Just create a new station ID. You can have as many as you want.
Height above ground is different and that you can control. As it relates to Weather Underground your height above ground is the height of your anemometer.
In regards to other weather sites that you may report weather data to, then you must understand what they are asking from you as it may differ from what WU is asking.
Thanks for the answer !! I was hoping I could just change mine because with all the stations around me are 200 to 300 feet higher . I guess google or were ever WU gets there elevation from thinks I'm in a deep hollow lol lol . I live in the flat desert so that's impossible .
Your elevation is 2850 Ft. I got that from several sources not from WU. But WU has the correct information in your case. It seems to me like WU has good data regarding your location. The stations around you Victorville as there is not much to the north of you are not more than 100 feet higher. I don't see anyone 200 feet higher. Besides your neighbors having different elevation I don't see what the problem is. The whole point of comparing station to station based on Sea Level Pressure is so that you can ignore differences in elevation between you and your neighbors. It puts everyone on equal ground....literally.
If your barometer is calibrated "correctly" to your elevation it doesn't matter that your neighbors are 100 or 200 feet higher. I say calibrated "correctly" because this means you have taken into account what your correct elevation is without using your neighbors as reference. You are about 30 feet lower than KVCV airport. But that doesn't matter. Your station pressure (absolute pressure) will be different ....but nobody reports that absolute number.....your adjusted Sea Level Pressures should be the same even though your elevations are slightly different.
Bottom line is this. I'm hearing you say you want to change your elevation to be 200 feet higher because your neighbors are at that elevation and you thin you are on flat ground and you think you are not in a hole. If so this is the wrong approach. Please provide some station IDs that are 200 feet higher so I can take a closer look.
