Item Identification

Title: Sea Surface Height
Short Name: ssh_annual_mean
Status: Completed
Abstract:

Monthly and annual summary of global sea surface height anomalies above mean sea surface, averaged from raw data. Raw data available from Oct. 2, 1992 to May 14, 2016, at 5 day intervals, with a spatial resolution of 0.17 degrees (Latitude) x 0.17 degrees (Longitude). Dataset contains the fully corrected heights, in meters.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.

Supplemental Information:

The native coordinate system for this layer is WGS 1984 World Mercator (ESPG: 3395). Please note: all MarineCadastre.gov data served by the NOAA Office for Coastal Management and hosted through Esri REST services are in the WGS 1984 Web Mercator Auxiliary Sphere (EPSG: 3857) projection.

Process Steps

Process Step 1

CC ID: 792291
Description:

(1) Data were downloaded from: https://podaac-www.jpl.nasa.gov/dataset/SEA_SURFACE_HEIGHT_ALT_GRIDS_L4_2SATS_5DAY_6THDEG_V_JPL1609?ids=Measurement:ProcessingLevel&values=Sea%20Surface%20Topography:*4*. (2) NetCDFs were converted to raster datasets (in total 1,725 Files, ~26 GB). (3) From the 5 day global composites, a monthly mean for every year was generated. (4) The monthly means were averaged together for all years (1992-2016) so that each month of the year has a Mean, Min, Max, and STD raster data layer. (5) Additionally the monthly averaged data were averaged by year, and all years 1993-2015 (n=23) were averaged together generating a raster for the Mean, Min, Max, and STD (1992 and 2016 were excluded due to missing monthly data which may skew the results).
