Retrieving accurate precipitable water vapor based on GNSS multi-antenna PPP with an ocean-based dynamic experiment

GNSS-derived PWVs during a 4-day shipborne experiment are included in this repository. There are four solutions with four different processing strategies, namely PPP without constraints (Conventional), with baseline length constraint only (Bl), with common ZTD constraint only (Com), and with both baseline length and common ZTD constraints (Bl+Com). The suffix 'Smooth' in the file names represents the PWV results after backward smoothing.
