Overview


This document outlines data reporting requirements for the Light Detection And Ranging (LIDAR) systems of the Network for the Detection of Atmospheric Composition Change (NDACC). These guidelines were developed by the LIDAR Working Group of the NDACC and the Aura Validation Data Center (AVDC) to facilitate the submission of LIDAR datasets compliant to the Generic Earth Observation Metdata Standard (GEOMS) to the Aura Validation Data Center (AVDC) and the NDACC Data Handling Facility (DHF).

Template description

  • Instrument Naming
    • Although LIDAR systems have the capability to measure multiple entities simultaneously, the instrument names of the different LIDAR systems are based on the primary measured entity to be reported in the file, as shown in Data Source Table below.

  • Variable Reporting - Ozone
    • For a LIDAR retrieving ozone using differential absorption, a list of variables is required as shown in the Table below. The reference temperature and the reference pressure profiles are reported in support of the determination of the ozone mixing ratio. These variables may be derived from LIDAR measurements or originate from external sources such as model analysis or radiosondes.

  • Variable Reporting - Temperature
    • The reporting of temperature data from LIDAR measurements requires variables as listed in the Table below.

    Notes
    [PRESSURE|DENSITY|AIR.NUMBER.DENSITY]_INDEPENDENT_NORMALIZATION - Depending on the retrieval codes, the corrected LIDAR signals, once proportional to atmospheric density, might or might not be normalized to an external atmospheric density value taken at the specified altitude from ALTITUDE_INDEPENDENT_NORMALIZATION. This value is usually taken from a model or radiosonde measurement, and the reference quantity is either pressure, density or number density. The data originator shall include in this variable only the quantity used in his/her retrieval.
    [PRESSURE|TEMPERATURE]_INDEPENDENT_INITIALIZATION - Depending on the retrieval codes, the retrieved LIDAR relative density profile will be integrated from the top using the hydrostatic balance, and using a "seed" temperature or pressure value taken at the altitude specified in variable ALTITUDE_INDEPENDENT_INITIALIZATION. This process is often called "initialization". The seed pressure or temperature value is usually taken from a model, an independent Sodium LIDAR temperature, or an independent satellite measurement. Data originator shall include in variable [PRESSURE|DENSITY|AIR.NUMBER.DENSITY]_INDEPENDENT_NORMALIZATION only the quantity used in his/her retrieval, e.g., either pressure or temperature.

  • Variable Reporting - Water Vapor (Raman)
    • From v004 the template has been renamed LIDAR.H2O. Note that the reference temperature and reference pressure profiles are reported in support of the determination of the relative humidity. These usually originate from external sources such as model analysis or radiosondes.

  • Variable Reporting - Water Vapor (DIAL)
    • The reporting of water vapor data from DIAL measurements requires additional investigation by the LIDAR Working Group.

  • Variable Reporting - Aerosol
    • An aerosol measurement template has been introduced from August 2016.

  • Additional Notes
    • The variable MJD2K is the Modified Julian Day Fraction, starting on January, 1st, 2000 at 00:00:00 UTC. The variable DATETIME is a single weighted mean time of the measurement, e.g. after accounting for periods where there is no data acquisition because of poor weather conditions, calibrations etc. The variable INTEGRATION.TIME is the effective integration time of the data used in the retrieval, which will be less than - or equal to - the difference between the start and stop times (after accounting for data acquisition gaps). Reported altitude ranges: The altitude range (e.g., min and max altitudes) will be determined by that of the primary measured variables. If other variables are undefined over part of this range, fill values (see section 8.9) should be used.

  • Variable Fill Values
    • The variable fill value is a number inserted as a substitute data element if a data element of a variable is default or missing.

  • File Granularity
    • The reporting granularity for LIDAR system measurements is one file per measurement.

  • Metadata - Global Attributes
    • Each LIDAR.[*] file requires one set of Global Attributes. These have been grouped in to three categories describing the file contents, namely Originator Attributes, Dataset Attributes and File Attributes. An example of a LIDAR ozone global attributes measurement at GSFC is given in Table .

  • Metadata - Variable Attributes
    • Each variable reported in a LIDAR.[*] file requires one set of Variable Attributes. These have been grouped into two categories describing the variable, namely the Variable Description Attributes and the Variable Visualization Attributes. An example of an attribute set is given in Table .
