i have 61 lat and 61 lon and 122 time ,under this condition i need to make pcolor plot for mean rain fall.i have already a code for the rain fall data.i just need the code for a standerd plot

Hi,
To create a standard “pcolor” plot in MATLAB for mean rainfall data, given that you have 61 latitudes, 61 longitudes, and data across 122 different times, you first need to compute the mean rainfall across all time points for each latitude and longitude.
Assuming you have your rainfall data in a 3D array where dimensions correspond to latitude, longitude, and time respectively, you can use the following MATLAB code to plot the mean rainfall using “pcolor” function:
% Assuming rainfall_data is your [61 x 61 x 122] array
rainfall_data = rand(61, 61, 122); % Example data, replace with your actual data
% Calculate the mean across the time dimension
mean_rainfall = mean(rainfall_data, 3);
% Generate lat and lon arrays assuming they are evenly spaced and known
% Replace these with your actual lat and lon values if they are available
lat = linspace(-90, 90, 61); % Example latitudes, adjust as necessary
lon = linspace(-180, 180, 61); % Example longitudes, adjust as necessary
% Create a pcolor plot
figure; % Open a new figure window
pcolor(lon, lat, mean_rainfall);
shading interp; % Optional: Makes the color smoother
% Adding enhancements for better visualization
colorbar; % Adds a color bar to indicate the scale of rainfall
title('Mean Rainfall'); % Adds a title to the plot
xlabel('Longitude'); % Label for the x-axis
ylabel('Latitude'); % Label for the y-axis
I hope the information provided above is helpful.
