【记录】CALIPSO数据产品命名规则

CALIPSO数据产品命名规则

这里只关注CALIPSO中的CALIOP激光雷达的数据产品，下图是CALIPSO数据产品中的命名规则。

这篇博客里使用的是气溶胶数据，数据为“CAL_LID_L2_05kmAPro-Prov-V3-01.2010-04-17T20-09-13ZN.hdf”，根据上图命名规则，我们可以知道，这个数据是CALIPSO激光雷达CALIOP的Level2 5km分辨率的气溶胶廓线产品，版本是V3，发布时间是2010年4月17日20时9分13秒白天的观测数据。知道了这个我们就可以更有针对性的对HDF数据进行读取理解了。

File Naming Convention (v4.x)

The CALIPSO data product naming convention is defined as:

[Investigation] _ [Subsystem] _ [Level] _ [ProductID]-[ProductionStrategy]-[Version].[Instance].hdf

其中：
Investigation = Mission Name: CAL
Subsystem = LID | IIR | WFC
Level = Product Level: L0 | L1 | L2 | L3 | L15
ProductID = Product Identification: 1Km | 125m | VFM | 333mCLay | 01kmCLay |
05kmCLay | 05kmALay | 05kmAProCal | 05kmCPro | PSCMask |
Ice_Cloud | Stratospheric_APro |
ProductionStrategy = Test | Beta | Quick Look | Expedited | Standard
Version = Version Information, e.g., V4-10
Instance = YYYY-MM-DDThh-mm-ssZ[D|N] | YYYY-MM[D|N|A] | YYYY-MM
File Format = Hiearchical Data Format: .hdf

例子: CAL_LID_L1-Standard-V4-10.2010-04-17T20-09-13ZN.hdf

Investigation

• CAL (CALIPSO mission)

Subsystem

• LID (Lidar)

Level

• L1

Product ID

• none for level 1 data

Production Strategy

• Standard

Version

• V4-10

Instance:

The data product version information is defined using the X.YY format, where
X - Major Release Number

• tracks a major software release

YY - Minor Release Number

• tracks a minor software release, e.g., change in GMAO data version,
  code or algorithm updates
