We report the experimental observation of sublattice-resolved resonantscattering in bilayer graphene by performing simultaneous cryogenic atomichydrogen doping and electron transport measurements in ultrahigh vacuum. Thisallows us to monitor the hydrogen adsorption on the different sublattices ofbilayer graphene without atomic-scale microscopy. Specifically, we detect twodistinct resonant scattering peaks in the gate-dependent resistance, whichevolve as a function of atomic hydrogen dosage. Theoretical calculations showthat one of the peaks originates from resonant scattering by hydrogen adatomson the {\alpha}-sublattice (dimer site) while the other originates fromhydrogen adatoms on the \b{eta}-sublattice (non-dimer site), thereby enabling amethod for characterizing the relative sublattice occupancy via transportmeasurements. Utilizing this new capability, we investigate the adsorption andthermal desorption of hydrogen adatoms via controlled annealing and concludethat hydrogen adsorption on the \b{eta}-sublattice is energetically favored.Through site-selective desorption from the {\alpha}-sublattice, we realizehydrogen doping with adatoms primarily on a single sublattice, which is highlydesired for generating ferromagnetism.
