The overarching goal of the California Underwater Glider Network is to sustain baseline observations of climate variability off the coast of California. The technical approach is to deploy autonomous underwater gliders in a network to provide real-time data.\nThe CUGN uses Spray underwater gliders making repeated dives from the surface to 500 m and back, repeating the cycle every 3 hours, and traveling 3 km in the horizontal during that time. The CUGN includes gliders on three of the traditional cross-shore California Cooperative Oceanic Fisheries Investigations (CalCOFI) lines: line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point.\n The glider missions typically last about 100 days, and cover over 2000 km, thus providing 4-6 sections on lines extending 300-500 km offshore. Since 2005 the CUGN has covered 200,000 km over ground in 28 glider-years, while doing 90,000 dives.\n\ncdm_data_type = TrajectoryProfile\nVARIABLES:\nprofile\nmission (Mission name of each trajectory)\ndepth (m)\nlatitude (degrees_north)\nlongitude (degrees_east)\nlat_uv (Latitude, degrees_north)\nlon_uv (Longitude, degrees_east)\nu_depth_mean (Depth-Averaged Eastward Sea Water Velocity, m s-1)\nv_depth_mean (Depth-Averaged Northward Sea Water Velocity, m s-1)\ntemperature (Sea Water Temperature, degree_C)\nsalinity (Sea Water Salinity, 1)\nchlorophyll_a (Chlorophyll-a concentration, mg m-3)\ndoxy (Dissolved oxygen, micromol kg-1)\nu (Eastward Sea Water Velocity, m s-1)\nv (Northward Sea Water Velocity, m s-1)\nacoustic_backscatter (dB)\n...

These files are 8 day composites of merged sensor (MERIS, Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua, Sea-Wide Field-of-View Sensor (SeaWiFS) Local Area Coverage (LAC) & Global Area Coverage (GAC), Visible and Infrared Imager/Radiometer Suite (VIIRS), OLCI) products.  MODIS Aqua and SeaWiFS were band-shifted and bias-corrected to MERIS bands and values using a temporally and spatially varying scheme based on the overlap years of 2003-2007.  VIIRS was band-shifted and bias-corrected in a second stage against the MODIS Rrs that had already been corrected to MERIS levels, for the overlap period 2012-2013; and at the third stage OLCI was bias corrected against already corrected MODIS, for overlap period 2016-07-01 to 2019-06-30.  VIIRS, MODIS, SeaWiFS and MERIS Rrs were derived from a combination of NASA's l2gen (for basic sensor geometry corrections, etc) and HYGEOS Polymer v4.12 (for atmospheric correction). OLCI Rrs were sourced at L1b (already geometrically corrected) and processed with polymer.  The Rrs were binned to a sinusoidal 4km level-3 grid, and later to 4km geographic projection, by Brockmann Consult's SNAP.  Derived products were generally computed with the standard algorithmsthrough SeaDAS.  QAA IOPs were derived using the standard SeaDAS algorithm but with a modified backscattering table to match that used in the bandshifting.  The final chlorophyll is a combination of OCI, OCI2, OC2 and OCx, depending on the water class memberships.  Uncertainty estimates were added using the fuzzy water classifier and uncertainty estimation algorithm of Tim Moore as documented in Jackson et al (2017). and updated accorsing to Jackson et al.
