i NASA ECCO - Analysis Tool

ECCO Analysis Tool

The ECCO Analysis Tool has been designed to allow for quick-look comparisons and analysis of various ECCO outputs. The ECCO outputs range from fluxes of freshwater, heat, and mass, to sea ice area, salinity, and sea surface topography. Latest ECCO products are interpolated to a ½ by ½ degree grid. ECCO products can be downloaded through the database for further analysis. Data span is January 1992-December 2017.

What Can You Do?
View and compare layers. Select one or more layers and adjust visibility by controlling opacity and work with a region of interest.
Draw a box or drop a pin with analysis tools to get statistics (min, max, standard deviation, trend, correlation) on data values. Analyze and compare time series, plot the area averaged time series up to two datasets for comparison, and apply filters to look at non-seasonal, high- and low-frequency signals.
Animate layers over time. Select a time period and interval. Synchronize the map with analysis time series.
Plot the data on a 3D Globe.
