Dataset description

This dataset contains maps of inundation fraction that were derived from NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission. Data span from March 17, 2017 - present and are at a 3 km spatial resolution, with daily files that represent the mean inundation fraction for the current day and previous two days. Due to the orbit of CYGNSS, data are only available from +/-38 degrees latitude, and missing cells are spatially interpolated. A subset of the data are hosted on this public server as netcdf files, though submission to the GEE community catalog would be as geo tiff and updated to present day.

The dataset has been described in this peer reviewed paper, and the model used to create the retrievals was validated and peer reviewed as well.

We would like to submit the dataset to the community catalog to increase the ease of access and manipulation of the data by end users.

Happy to work on this @claraatmuon but I would love some information here

• Did you say you will be providing the data as geotiffs for ingestions?
• What is the estimates size across all geotiffs?
• Any page that mentions the license would be great as well

Looking forward to this

Hi Samapriya, Yes, although the original dataset was in netcdf form, we understand that geotiffs would be more easily ingested into GEE, and so we would plan on converting all of the files into geotiffs. If COGs are better, let us know, and we could explore converting the netcdfs into COGs instead. For 8 or so years of data, we estimate ~5.5 GB if the data are provided with no data quality band, or ~11 GB if we include the data quality band. We would be interested to hear your experience with whether or not users of GEE prefer having data with a quality band or not, or if the size of the dataset is excessively large. We unfortunately didn't release the original dataset with any licensing information. The dataset was a funded effort through a NASA ROSES proposal, and so the data are free and open to the public. Let me know what other information I can provide! Thank you, Clara

That sounds great, please let me know when you have processed the geotifs and where I can access them. It would be great to have any metadata attached to each file as well. Feel free to include the quality band I think it will be useful and that is not a large difference in size relative to the catalog

[claraatmuon]

Thanks, we will do that! Just FYI, with Thanksgiving and AGU coming up, we may not be able to send the dataset until mid-December, but we'll start converting all the netcdf to geotiffs soon! Best, Clara
