Luka Catipovic - Project

Hi, for this project I'm interested in looking at very high spatial resolution multi-band reflectance data to look at the interface between rivers and coasts. Capturing rates of transport, consumption, and flocculation of terrigenous material is very difficult to do with in-situ sampling and I believe strong analysis can be made from remote sensing data products to help interpolate between measurements made by hand

RE: Luka Catipovic - Project

As I sort through the data available in the ERDDAP database, I see a very limited number of options of data products suitable for answering the type of question proposed above. What I was hoping to have access to through his portal was level 2 reflectance data from all available bands from a sensor such as worldview as mentioned in the introductory video. So, I think I will have to repose my question now seeing what is available.

As much of what is listed on ERDDAP is very course spectral and spatial resolution. I've decided that a historical study is most within the scope of this course. Using the Sea Ice Concentration, NOAA/NSIDC Climate Data Record V3, Arctic, 25km, Science Quality, 1978-2019, Monthly I propose to do a seasonal study investigating the relative timing of ice breakup and formation in the Arctic Ocean from year to year. I'm specifically interested in the North Alaskan coastline as many of the rivers draining the North Slope flow under the land-fast ice before breakup occurs.

Hi Luka - 

Sorry you are not finding the data that you were hoping to find.  The Worldview sensor is very high resolution, and is commercial, so one has to purchase the data, so it is not something that we serve.  We do have level 2 reflectance data from VIIRS at 750 m available on thredds: 

Level-2:

We also have this data available as level 3 data on ERDDAP which will be a little easier to access:

Yes, this course focuses on Level 3 and 4 data. The highest resolution L3 data we serve for sea ice is VIIRS at 750m:

https://www.star.nesdis.noaa.gov/socd/lsa/SeaIce/

This is available on PolarWatch: https://polarwatch.noaa.gov/catalog/?ice=y&searchFor=viirs+ice

L1 and 2 data are available through CoastWatch Central and the NESDIS/STAR science teams, they just aren't the focus of this course. Here are the data discovery/viewers available through CoastWatch. Reach out to instructor Michael Soracco with questions about L1/L2 data available through CoastWatch and the coastwatch utilities software for working with these data types.
