% run ncdisp('data.nc') to view variables and dimensions

% Read in variables from file data.nc
PRCP = ncread('data.nc','PRCP');
% Now use PRCP[day,station] to access precip (inches)

% The other variables are just one-dimensional indices
% Perhaps these WBAN station numbers mean something ... (??)
WBAN = ncread('data.nc','WBAN');
T = ncread('data.nc','T'); % T is just the day index
