map Time Smoothing for Giovanni-3
Entry ID: G3_mapTimeSmoothing
Abstract: The mapTimeSmooth service for G3 takes a series of grids as an input and
computes a series of smoothed grids as the output. The output values are the
result of applying a simple boxcar filter to the series of input grids, where
the units of the filtering dimension are individual files.
Output ... Description:
Smoothed variable array
Same as input parameters
Input and output files are in HDF4.
Essentially this service is performed by repeated applications of the map Time
Average service. since the filter window moves, there is usually more than one
output grid produced.
he averaging service takes care of the required subsetting and weighting,
while the smoothing service merely acts as a controlling element, passing
the sets of files for each smoothing window to the averaging service, along
with the required weighting and geographic subsetting parameters.
The averaging service also handles the details of collapsing three-
dimensional input arrays into two-dimensional arrays.
Implemented in IDL
This document describes only the mathematical approach used in the computation.
Quality Data quality is dependent on input data sets and processing.
Access Constraints There are no access constraints to data in Giovanni-3.
Use Constraints Use of the data and the Giovanni system should be acknowledged in published works and presentations.
