经纬度,时间参数什么的都能理解,但是不明白climatology_bounds,longitude_bounds ,latitude_bounds 是什么意思,跪求大家帮忙~~~
他们读出来的数据分别是这样的:
latitude_bounds的数据把纬度从-90到+88.75列了第1行,又从-88.76到+90列了第2行(间距2.5)
longitude_bounds 的数据把经度从-181.87498到+174.37502列了第1行,又从-178.12502到+178.12498列了第二行(间距3.75)
climatology_bounds更诡异。。。是长这样的:
1 32 60 91 121 152 182 213 244 274 305 335
10624 10652 10683 10713 10744 10774 10805 10836 10866 10897 10927 10958
这些都是什么玩意儿 新人渣表示很困惑。有木有大神来指点迷津,谢谢谢谢
