Upgrades around Oct. 13
Filed under English versionDear all,
During these days, I received dozen of emails with praises and encourages. Thank you for your all! As programing is a tire work and sometimes boring, your support is one of the *most* important things!
Recently I have made (or will be made very soon) some upgrades of the system which you may have noted. They are
1) enhancement of APanel lon/lat function. I have received some complaints, include several old users, about the error of APanel. That’s because the resolution of GFS is not high enough. If the surrounding on altitude of your site is “flat” enough, you may not suffer from this problem. However, if you are on a peak that is significantly higher than your surroudings, you may find that the forecast is far from satisfied, as the grid of GFS is 35×35km and the data is about an average of a 35×35km region around you. To fix this problem, a new parameter named “Altitude Correction” is introduced. This only takes effect on lon/lat query method, for those who are selecting site from database, Altitude Correction does not works.
2) Complete version of site data. In the former version, the site of Russia and U.S. was not included without a note, and I should apologize for those who came from these two countries. For site data of Russia, the raw data from NGA is far too big (~84M) and the conversion loop cannot work on it; For U.S., that’s because it uses the data from USGS, not NGA, and the format is different. Thus, I have to wrote another special conversion loop for it. The two loops are written today, and the conversion is now on process. If all goes right then the site file of the two countries will be added early tomorrow.
3) “Weachart” product (provide meteorological charts for a great variety elements) is now under partial test and is only available to Chinese users. There are a number of guys from weather bureau put some good words on it and I’m on bug fixes and model refines. However I met some obstacles with difficulties to go over it and I cannot give an exact date of when can it be okay for a public test.
Okay… so much for this. I’ve a few lines more to write but now I should go to sleep now.
Happy using!

Hi I’m looking forward to your new developments! I do have one question though, maybe I’m not doing it right…
I’m trying to look at the worldwide cloudcover chart for 7 days from now ie 25th Oct 18:00 UTC. The site does produce a map, but it seems to be today’s one. The old 7timer included the date and time on the map itself, which was useful to confirm, and also to save the image and look at it later. I have the same problem with the animation- it shows clouds moving, but I can’t see what the date and time are. Is there something I’m doing wrong?
Regards,
Simon

Hi Simon, I suppose that’s me who had done something wrong — the “Weachart” section is not open yet, and it’s only available for test for Chinese users. But you could easily access it by built-in search, as I have upload the files to the server. I shouldn’t be so careless (although Miss. Shi had pointed this to me)
I’m still work on it, and hopefully it will be fine enough for public test before Monday. I have to warn you that the graph *may* be completely wrong! I’ll update the blog tomorrow once I have fix these things.
Best regards,
Quanzhi
