全天候、全天时、高精度的定位 (all time, all weather and high-accuracy positioning) Hi everyone, Last night I saw a news in the paper and I found something wrong that the word"all-weather" and the word"all-day" is not the same meaning. And the word "all-time" means the changes in a day... Do not make calls to action directed at non-public persons, or post information with the purposes of causing harm or harassment. This includes but is not limited to: names, telephone numbers, street or email address, or hinting that you have this information. If you have evidence that someone is a shill, spammer, manipulator or otherwise, message the moderators so we can take action. Public accusations are not okay. Do not use a username mention, regardless of context. The Hourly Weather Forecast graphs out temp/dewpoint, wind, rain/snow, etc., which is really handy if you wanna get a quick idea of what to expect at a given time. The Forecast Discussion can be a bit technical for beginners, but it's usually pretty in -depth and can help you learn why things are happening instead of just what is happening. You'll also be able to see any watches, warnings and other alerts that are active in your area. Weather Underground has, by far, the best data and accuracy, in part because it has a network of tens of thousands of personal weather stations (PWS). This is where the micro-climate thing comes in . Wunderground is the only app where you can really see the difference between here and 3 miles from here.
