The confidence intervals are the standard CI’s corrected for auto-correlation. Notice the larger uncertainty in the coefficients for the satellite-data, caused by higher auto-correlation and bigger swings in the data.
The preRS is similar to the normal RS but penalizes for variates that do not contribute to the regression enough.
