NAmerica:0.125deg:2002-:7D:Groundwater and soil moisture from GRACE

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.

Description/Name	Spatial	Time
Groundwater and Soil Moisture Conditions from GRACE Data Assimilation GRACEDADM_CLSM0125US_7D V4.0	0.125x0.125 degree -125, 25 to -67, 53	7 day 2002-10-04 to recent

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:

  LDAS “variables” string Description	Units
  GRACEDADM_CLSM0125US_7D.4:gws_inst Groundwater storage percentile	percent
  GRACEDADM_CLSM0125US_7D.4:rtzsm_inst Root zone soil moisture percentile	percent
  GRACEDADM_CLSM0125US_7D.4:sfsm_inst Surface soil moisture percentile	percent

• 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”.
