Global stacked sea surface height profiles from AltiKa satellite altimeter data (NCEI Accession 0174134)

NetCDF file result_stack.nc contains longitude, latitude, number of cycles, sigma, and stacked sea surface height records for 1002 AltiKa satellite altimeter passes. Repeat cycles were aligned to a common position along a synthetic track having 20005 records between +/-81.498 latitude with equator crossings from the AltiKa median equator crossing table. Stacking is the median sea surface height profile from multiple repeat cycles. Sigma is the expected one sigma error in a single measurement. The number of cycles is the quantity that passed selection criteria and were included in a stack. Cycles were restricted to 1 through 32 due to orbital drift off the nominal ground track after a hardware issue in 2015.
