MODIS Web Service

MODIS

Developmental service. This service is internal CUAHSI use, and evaluation.

MODIS is a product provided by NASA featuring time series of atmospheric data. This web service provides methods for retrieving data from MODIS. For more information about MODIS, see http://g0dup05u.ecs.nasa.gov/Giovanni/modis.MOD08_M3.shtml

The following operations are supported. For a formal definition, please review the Service Description.

GetValues
This function returns a string formatted as XML containing NASA MOVAS time series data. The data are spatially averaged over the extent specified by the bounding lat/lon coordinates. The data are temporally averaged with a monthly time step.
The dataset begins at March 1, 2000. The end of the available data will change over time. It usually is 6 months to a year behind.
Valid VariableCode values include:
    0 - Aerosol Optical Depth at 0.55 Micron
    1 - Aerosol Fine Mode Fraction
    2 - Fine Mode Aerosol Optical Depth (Ocean)
    3 - Cirrus Fraction NIR Method
    4 - Cirrus Reflectance
    5 - Cloud Fraction Daytime IR Method
    6 - Cloud Effective Radius Combined Phase (QA WT)
    7 - Cloud Effective Radius Ice Phase (QA WT)
    8 - Cloud Effective Radius Water Phase (QA WT)
    9 - Cloud Optical Thickness Combined Phase (QA WT)
    10 - Cloud Optical Thickness Ice Phase (QA WT)
    11 - Cloud Optical Thickness Water Phase (QA WT)
    12 - Cloud Top Pressure
    13 - Cloud Top Temperature
    14 - Water Vapor Clear Sky NIR Method
    15 - Water Vapor Above Cloud NIR Method
    16 - Water Vapor Column IR Method (QA WT)
    17 - Corrected Fire Pixel Count

Valid PlotArea values include:
    landocean - spatial averaging includes land and ocean
    ocean - spatial averaging includes only ocean
    land - spatial averaging includes only land
Test arguments: GetValues("GEOM:BOX(-180 -90,180 90)", "MODIS:11/plotarea=landocean", 2000-10-01, 2001-12-01, "" )

GetVariableInfo
Given a variable code, this method returns the variable's name. Pass in the variable in this format: 'NetworkName:Variable'

GetVariableInfoObject
Given a variable code, this method returns the variable's siteName. Pass in the variable in this format: 'NetworkName:Variable'
