    "title": "ESA River Discharge Climate Change Initiative (RD_cci):  Altimetry-based River Discharge product, v2.0",
    "abstract": "This dataset comprises the altimetry-based river discharge (RD-alti) Climate Research Data Package (CRDP) v2.0, developed under the ESA CCI River Discharge precursor project phase 2 (RD_cci+). The dataset, produced by a consortium including Hydro Matters, LEGOS, and EOLA, provides long-term satellite-derived river discharge time series spanning 2002 to 2022 at designated locations.\r\n\r\nThe methodology, detailed in the associated ATBD (Algorithm Theoretical Baseline Document), generates two distinct RD-alti products:\r\n1.\tStation-level discharge estimates: A rating curve has been established for each station using a calibration period based on in-situ discharge time series and merged Water Surface Elevation (WSE) time series. This rating curve was then applied to the entire merged WSE series to produce a continuous river discharge (RD) time series per station.\r\n2.\tMission-track-specific discharge estimates: For each station, independent rating curves were derived for individual satellite mission-tracks, using the same calibration period. These rating curves were computed between in-situ discharge time series and single-mission WSE time series, then applied to the full single-mission WSE dataset to generate river discharge estimates per mission-track and per station.\r\n\r\nThe resulting CRDP delivers two complementary river discharge products, enabling robust analysis of river discharge dynamics over two decades.",
