Data organization

The data are organized in a gridded data structure, i.e. data cubes. The tiles manifest as directories in the file system, and the images are stored within. For mosaicking, use force-mosaic.

Data Cube definition

The spatial data cube definition is appended to each data cube, i.e. to each directory containing tiled datasets, see Data Cube definition.

File format

Refer to Output format for details on the file format and metadata.

Naming convention

Following 41-digit naming convention is applied to all output files:

Example filename: 2000-2010_001-365-03_HL_CSO_LNDLG_NUM.tif

There are several product types available, all are optional. The Number of Observations (NUM) product contains the number of clear sky observations for each pixel and bin. The other products are statistical summaries of the temporal difference (dt) between consecutive observations within these bins.

Clear Sky Observation Statistcs

Currently available statistics are the number of observations, and aggregate statistics of the temporal difference between observations (available are average, standard deviation, minimum, maximum, range, skewness, kurtosis, any quantile from 1-99%, and interquartile range.
