Photosynthetically Active Radiation Data

[polczynskim]

I am new to your services and need some assistance in navigating your website. I am looking to download daily photosynthetically active radiation (PAR) data for 2019-2022 for Door County, Wisconsin (specifically 45.06499, -87.12427). We are doing an orchid restoration project at The Ridges Sanctuary (https://www.ridgessanctuary.org/research/orchid-restoration-project/) and would like to have a PAR baseline to compare our on-site PAR measurements.

Thank you for any assistance you can provide.

Hi @polczynskim, All PAR data products available are listed here: https://search.earthdata.nasa.gov/search?fs10=Photosynthetically+Active+Radiation&fsm0=Vegetation&fst0=Biosphere

In addition, MCD18A2/MCD18C2 provide daily PAR: https://search.earthdata.nasa.gov/search?q=mcd18

Thanks for the quick response. I got to the websites, and am now trying to figure out how to download the exact data I am looking for. By any chance, is there a tutorial that might help me out?

@polczynskim, The available data tools and services vary depending on the product. Can you share which product(s) you are interested in?

MERRA-2 PAR products are in our Giovanni system, and that provides an opportunity to make a quick analysis for a particular region such as Door County. For Door County in particular, you would have to make a bounding box, or you could do the state of Wisconsin and just look at the values visually. I would suggest making a small bounding box centered on your region of interest and creating a time series which allows you to see the values in a CSV file over a period of time.
