<pre style="background-color: rgb(255, 255, 255);" class="">I want to make time series plot for multiple files with different time resolutions.</pre>
<pre style="background-color: rgb(255, 255, 255);" class="">The file with coarse resolution has monthly accumulation precipitation, while the one with fine resolution has daily precipitation. Both of them have 16 years of data. I can do the grid interpolation (see the first attachment), and also write a separate script to convert monthly data to daily precipitation because different months has different days (attachment 2), but how to combine them to make daily time series plots for the whole time period? Or maybe there is one command to convert monthly data to daily directly using Grads? Thank you very much.</pre>
