hi, i am currently working on tropomi data and the i am trying to read the nitrogendioxide tropospheric column data from the NetCDF file. however the column data is not saved under variables but is saved under variables in the Group folder. the variable path is like this Groups:/PRODUCTS/Variables: nitrogendioxide_tropospheric_column. what code can i use to read this variable. i already tried ncread(tropomi,'nitrogendioxide_tropospheric_column') but it gave an error saying the variable doesnt exist in the file. kindly help me to read this data

file1 = 'tropomi1.nc' ;
file2 = 'tropomi2.nc' ;
x1 = ncread(file1,'/PRODUCT/longitude');
y1 = ncread(file1,'/PRODUCT/latitude');
z1 = ncread(file1,'/PRODUCT/nitrogendioxide_tropospheric_column') ;
x2 = ncread(file2,'/PRODUCT/longitude');
y2 = ncread(file2,'/PRODUCT/latitude');
z2 = ncread(file2,'/PRODUCT/nitrogendioxide_tropospheric_column') ;
