title: Extract data of specific dates from NETCDF dataset
body: <p>I have netcdf data which contains daily for the year 2020 with specific humidity as the variable, and an excel file that contains the date of all the cyclones that formed over the North Indian Ocean. Mostly, when we want to extract data within a particular time range we use to do slice using xarray, but in this particular situation, I am facing the problem that I need to extract data only for those specific cyclone days which are in the excel file and create a composite. If anyone can help me by showing how it can be done it will be much appreciated.
  I am attaching a link to the netcdf dataset and the excel file containing the cyclone days.<a href="https://drive.google.com/file/d/1yqG7VqV7_wFcuLCg-RjcekJM-6pS-Zk9/view?usp=sharing" rel="nofollow noreferrer">netcdf</a> <a href="https://docs.google.com/spreadsheets/d/1T2qK2Ix4JNahyCYZ4vupVr9r6WbRI_FU/edit?usp=sharing&amp;ouid=104821943386697799157&amp;rtpof=true&amp;sd=true" rel="nofollow noreferrer">cyclonedays</a></p>
