now I would like to plot this data for every month according to my

why variations in accuracy between R to ARCGIS for the same point reprojection?
...t to Berhmann to ensure equal area distribution of the
points.
In R, I am using:
spPoint <-
SpatialPoints(coords=coordinates(Data),proj4string=CRS("+proj=longlat
+datum=WGS84"))
and then reprojecting it to Berhmann with:
spPointReprj=spTransform(Data,CRS("+proj=cea +lon_0=0 +lat_ts=30
+x_0=0 +y_0=0 +ellps=WGS84"))
If I put the two outputs of the reprojections in the same map, they
are off by few meters in the tropics by up to 40km in the poles.
I decided to investigate how the reprojections are done and my
calculations are different from both R and ArcGis:

Here is the code wich forms input matrix to make_stars function:
transpose_stars = function(lat_b, long_b,lat_t,long_t,step){
matrix <- readSO2Data(lat_b, long_b) // read an arbitrary point for
calculating matrix size
