The PO.DAAC is pleased to announce the public release of the Cyclone Global Navigation Satellite System (CYGNSS) data products from the CYGNSS science team including a level 3 ocean microplastic concentration v3.2 dataset. The datasets are provided in netCDF-4 format and extend from 1 August 2018 to the present with an approximate 6 day latency.
This dataset contains the version 3.2 CYGNSS Level 3 ocean microplastic concentration data record, which provides microplastic concentration on a daily temporal and 0.25-degree latitude/longitude spatial grid with 30-day, 1 degree latitude/longitude feature resolution, as constrained by the binning and spatiotemporal averaging of the Mean Square Slope (MSS) anomaly. Version 3.2 uses CYGNSS MSS measurements that are derived from updated v3.2 Level 1 scattering cross section data and has updated the parameterizations in the data processing algorithm to use v3.2 data correctly.
The CYGNSS datasets and documents are accessible via the dataset landing page on PO.DAAC web portal. Users are recommended to download the data using the podaac-data-subscriber. We also encourage users to visit PO.DAAC Cloud Cookbook for detailed information about how to access the data from NASA Earthdata Cloud. General information regarding the CYGNSS mission is available from the mission website.
