Data Pool Glossary
This glossary defines some words related to using the
Data Pool.
Chunk Size
The amount of data returned at one time.
DAAC
Distributed Active Archive Center
Data Product
A collection (one or more) of parameters packaged with
associated ancillary and labeling data.
Drill-down
Drill-down refers to the search process, or going deeper
into the hierarchy of search parameters to find data.
ECS
The EOSDIS Core System.
EOSDIS
EOSDIS is the Earth Observing System Data and Information
System. At present, EOSDIS manages data from NASA's Earth science
research satellites and field measurement programs, providing data
archival, distribution, and information management services. EOSDIS
commands and controls satellites and instruments, and generates
useful products from orbital observations. EOSDIS also generates
data sets by assimilating satellite and in situ observations into
global climate models.
ESDT
ESDT stands for Earth Science Data Type and is the primary
means by which EOSDIS identifies the major emphasis of the content
of a data collection. For example, MOD10A1.3 refers to the MODIS/Terra
Snow Cover Daily L3 Global 500m ISIN Grid, Version 3 data set.
Granule
The smallest aggregation of data that is independently
managed (described, inventoried, and retrieved) within the Data
Pool.
GranuleUR
A universal reference (UR) or unique identifier for a
granule. GranuleURs are unique across the ECS DAACs.
Metadata
A description of the content, format, and utility of a
data set.
NASA
National Aeronautics and Space Administration
ScienceQA
Also know as ScienceQualityFlag, this attribute has one
of six possible values reflecting the quality of the chosen Measured
Parameter.
Spatial Resolution
Indicates the level of granularity of the data.
