to_dataarray
使用to_dataarray弹出错误：
ValueError: coordinate 'time' is a DataArray dimension, but it has shape () rather than expected shape (1,) matching the dimension size
修改如下：
return xr.DataArray(self.data[None, :, :], coords={'time': [self.obs_start_datetime()],
'lat': self.lat, 'lon': self.lon},
dims=('time', 'lat', 'lon'), name=self.product_type)
不好意思，我就不pull request了.
数据块类型错误
AWX格点产品云顶亮度温度TBB应当被论断为无符号型，同时取质量控制下限和上限之间的值，需改正。
投影坐标是否准确？
Line 279 in 4b1e4da
我尝试读取Lambert投影的数据，也把投影中心当作图像中心，但是反算出来的经纬度范围和二级头信息中的经纬度范围不太匹配。
推测投影中心并不是图像中心。
NSMC的经纬度对照表格点数是512*512的不确定怎么缩放：http://satellite.nsmc.org.cn/PortalSite/StaticContent/DocumentDownload.aspx?TypeID=22
方便加QQ或者微信讨论下吗？
