各位好。非常高兴地向大家宣布一个十分重要的进展:今天经过反复试验,通过degrib的方法顺利对GRIB2格式的数据进行了解码。这些数据的精度达0.5度(约55公里),比现在7Timer!所用的GRIB1格式的数据精确8倍。附测试图片,2月4日北京时间20时的GFS自带云量输出图,可以对比一下新格式数据的效果。

  由于degrib对GRIB2的解码仍然不是非常好用,因此短期内新数据还不会正式投入使用。计划继续对7Timer!-ArP进行升级改造,提供更为智能的ArP运行信息。

Hi all, glad to announce a good news: the GRIB2 data has been successfully decoded. GRIB2 format raises the resolution to ~55km, which is eight time better than the currently-used GRIB1 format. Test images are shown here.

As the DEGRIB is not quite smoothly working with GrADS, I've no plan to put the GRIB2 data into use in near future. These days I plan to continue on evaluating 7Timer!-ArP.
