To save each converted file as a .asc file, you can use the "save" function.
clear all;
clc;
files = dir('*.nc');
outputDirectory = 'output_asc_files';
% Create the output directory if it doesn't exist
if ~exist(outputDirectory, 'dir')
mkdir(outputDirectory);
end
for k = 1:length(files)
ncfile = fullfile(files(k).folder, files(k).name);
SST = ncread(ncfile, 'SST');
SSSanomaly = ncread(ncfile, 'SSS_anom');
SSSuncorrected = ncread(ncfile, 'SSS_uncorr');
SSS = ncread(ncfile, 'SSS_corr');
Lat = ncread(ncfile, 'Latitude');
Lon = ncread(ncfile, 'Longitude');
Data = [Lat(:), Lon(:), SSS(:), SSSuncorrected(:), SSSanomaly(:), SST(:)];
id = (Lat >= 1 & Lat <= 2);
Data1 = Data(id, :);
% Extract the filename without the extension
[~, baseFileName, ~] = fileparts(ncfile);
% Create the output .asc filename
outputFileName = fullfile(outputDirectory, [baseFileName '.asc']);
% Save the data as an ASCII file
save(outputFileName, 'Data1', '-ASCII');
end
