global:0.25deg:2000-:3H:GLDAS NOAH hydrology model results

This will download data from a set of water cycle related variables (Table 1) from the North American and Global Land Data Assimilation Systems (NLDAS and GLDAS, respectively), the Land Parameter Parameter Model (LPRM), the Tropical Rainfall Measuring Mission (TRMM), and Gravity Recovery and Climate Experiment (GRACE) data assimilation. In addition to their access provided by the hydrology community tools, selected data rods variables can be searched and accessed through the GES DISC search and access user interface, and all data rods variables can be accessed via Web services developed by the GES DISC.

The time zone is always UTC.

Parameters:

  • lat (float) –

    Should use ‘lat’ and ‘lon’ to specify location.

    Latitude (required): Enter single geographic point by latitude.:

    Example: --lat=43.1

    If known, ‘xindex’ and ‘yindex’ can be used for the NLDAS grid only.

  • lon (float) –

    Should use ‘lat’ and ‘lon’ to specify location.

    Longitude (required): Enter single geographic point by longitude:

    Example: --lon=-85.3

    If known, ‘xindex’ and ‘yindex’ can be used for the NLDAS grid only.

  • xindex (int) –

    It lat or lon is None, then will try xindex and yindex.

    Enter the x index of the NLDAS grid.:

    Example: --xindex=301

  • yindex (int) –

    It lat or lon is None, then will try xindex and yindex.

    Enter the y index of the NLDAS grid.:

    Example: --yindex=80

  • variables (str) –

    Use the variable codes from the following table:

  • startDate (str) –

    The start date of the time series.:

    Example: --startDate=2001-01-01T05

    If startDate and endDate are None, returns the entire series.

  • endDate (str) –

    The end date of the time series.:

    Example: --endDate=2002-01-05T05

    If startDate and endDate are None, returns the entire series.

  • variable (str) – DEPRECATED: use “variables” instead to be consistent across “tsgettoolbox”.
