Gridded Point Data
Overview

McIDAS-V can create gridded fields of numeric data using the Barnes Objective Analysis. You can control the parameters used to create the grid from the Data Source Properties or using the Grid Parameters tab in the Data Subset panel of the Field Selector. Note that since this gridded display will utilize point observation data, the display over areas with few observations (ex. open ocean) may not correctly represent the actual data over that region. Also note that with certain point netCDF files where each data point has a different time, time binning must be applied to the data source before the display is created to group multiple times of data into the same timestep for gridded displays to be created. To get more exact gridded displays of point data, it is best to utilize the Region tab to subset an area of interest with a relatively high density of point observations:

The resulting grid can be displayed using any of the Gridded Data Displays.
