AST, 谁知道MODIS MYD06 product里面的"Surface_Type"是怎么规定的？
在相关的ATBD和FS都没有找到说明，这个FS只给出以下信息:
short Surface_Type(Cell_Along_Swath_5km:mod06,Cell_Across_Swath_5km:mod06) ;
Surface_Type:long_name = "Surface Type Based on Emissivity "
;
Surface_Type:units = "none" ;
Surface_Type:valid_range = 0s, 200s ;
Surface_Type:_FillValue = -32768s ;
Surface_Type:scale_factor = 1.0d ;
Surface_Type:add_offset = 0.0d ;

自问自答吧，好像有些同行业关注这个：
BTW: MODIS team 干吗不弄一个详细的正式说明呢？那个FS实在不够详细。
The "surface type" is an index from 0-100 that indicates ecosystem type
according to the Olson global ecosystem map. Here are the indecis and their
meanings:
Global Ecosystems Legend Value Description
1 Urban
2 Low Sparse Grassland
3 Coniferous Forest
4 Deciduous Conifer Forest
5 Deciduous Broadleaf Forest
6 Evergreen Broadleaf Forests
7 Tall Grasses and Shrubs
8 Bare Desert
9 Upland Tundra
10 Irrigated Grassland
11 Semi Desert
