Another change is that in the examples below, the values returned in the tibble for grid variable time are not the numeric values stored in the NCDF file, but instead character strings. However, selection of grid points seems still to work based on the numeric values. ]]> Using R https://www.r4photobiology.info/galleries/online-weather-data.html Sun, 30 Jul 2023 21:00:00 GMT
