ATLASICESAT-2 数据命名规则

Posted 2022-01-31 空中旋转篮球

数据文件使用以下命名约定:

以ATL08为例:

ATL08_20181014092931_02410101_005_01.h5

ATL08_[yyyymmdd][hhmmss]_[ttttccss]_[vvv_rr].h5 

文件命名约定变量说明如下表所示:

文件命名约定变量和描述

Variable	Description	描述
ATL08	ATLAS/ICESat-2 L3A Land and Vegetation Height product	ATLAS/ICESat-2 L3A陆地和植被高度产品
yyyymmdd	Year, month, and day of data acquisition	数据采集的年、月、日
hhmmss	Data acquisition start time, hour, minute, and second (UTC)	数据采集开始时间、小时、分钟和秒(UTC)
tttt	Four digit Reference Ground Track number. The ICESat-2 mission has 1,387 RGTs, numbered from 0001 to 1387.	四位参考地面轨道号。ICESat-2任务有1387个rgt，编号从0001到1387。
cc	Cycle Number. Each of the 1,387 RGTs is targeted in the polar regions once every 91 days. The cycle number tracks the number of 91-day periods that have elapsed since ICESat-2 entered the science orbit.	周期数。1387个RGTs每91天在极地地区出现一次。这一周期记录了自ICESat-2进入科学轨道以来经过的91天周期的数量。
ss	Orbital segment (region) number (see Figure 3). ATL08 data files cover approximately 1/14th of an orbit. Orbital segment numbers range from 01-14. Note: data files are not produced for orbital segments that cross open ocean only (i.e. do not cross a land surface). As such, some orbital segments will not available.	轨道段(区域)数(见图3)。ATL08数据文件大约覆盖轨道的1/14。轨道段数在01-14之间。注:数据文件不为仅穿越公海(即不穿越陆地表面)的轨道部分生成。因此，有些轨道段是不可用的。
vvv_rr	Version and revision number.*	版本和修订号
