Accessing NOAA tide data with R (updated 2021)
It’s been a decade since I wrote a script to retrieve observed tide height data from NOAA’s CO-OPS server, which lets you grab up to a month of tide data for a given tide station at a time. In that time, they’ve migrated over to a new server and slightly different API, so it’s probably…

Extracting NOAA sea surface temperatures with ncdf4
I’ve written previously about some example R scripts I created to extract sea surface temperature data from NOAA’s Optimum Interpolated Sea Surface Temperature products. If you want daily global sea surface temperatures on a 0.25×0.25° grid, they gather those into 1-year files available at http://www.esrl.noaa.gov/psd/data/gridded/data.noaa.oisst.v2.highres.html. If you want weekly average SST values on a 1×1°…

NOAA OISST v2 High Resolution daily sea surface temperatures with R
Update, 2015-11-30 It appears that NOAA has gone through and upgraded all of the OISST files to the newer version of the NetCDF file format. As a result, the functions outlined in this post don’t work any longer. Instead, see the updated functions in my newer post, https://lukemiller.org/index.php/2014/11/extracting-noaa-sea-surface-temperatures-with-ncdf4/. The concepts are the same as described…

Accessing NOAA tide data with R
Here’s some R code that can be used to download archived tide height data from NOAA’s CO-OPS OPeNDAP server. The code makes use of RCurl to send a URL query to the server, and then splits apart the resulting data into a data frame.
