[求助]请帮忙解释一下这个MODIS文件名的意思

<P>文件名为：MOD09GHK.A2000063.h26v04.004.2002356140642.hdf</P>
<P>能否解释一下这个文件名包含的信息。特别是GHK代表什么？A2000063中的A代表什么？h26v04又是什么意思？……</P>
<P>下面是在网上搜到的关于MODIS命名规则的资料：</P>
<P>MOD01.A2002032.1015.003.2002034184356.hdf </P>
<P>aaaaa bbbbccc dddd eee fffffffffffff ggg <BR>a) MODIS product short name, e.g. "MOD01" refers to the MODIS Level 1A Radiance product. "MOD" signifies </P>
<P>Terra/MODIS, whereas "MYD" signifies Aqua/MODIS. <BR>b) Year in which data was collected by the instrument, e.g. 2002. <BR>c) Day on which data was collected by the instrument, given in Day of Year. For example, "032" is February 1st, i.e. </P>
<P>the 32nd day of the year. <BR>d) Time at which data was collected, given in Universal Time Coordinate (UTC) or Greenwich Mean Time (GMT). <BR>e) Collection (version) number. <BR>f) Production date and time, given in year, day-of-year, hours, minutes, and seconds, in the form yyyydddhhmmss. <BR>g) File type extension, e.g. "hdf" is Hierarchical Data Format. All MODIS data are available in HDF format. <BR></P>
<P>根据资料的例子对应到我的文件来看，h26v04应该是dddd部分，代表的是时间（小时和分钟），看不懂这该是什么时间了。</P>
<P>请知道的尽量详细的解释一下好么？十分感谢！</P>

<P>多谢gis : )</P>
<P>h26v04代表的是图幅，a代表是上午。因为最多每天一幅，所以没有小时和分钟的纪录。</P>
