Short summary
We present development of a digital mobile solar tracker which can be coupled simultaneously to UV–Vis and FTIR spectrometers to measure trace gases in the atmosphere. We demonstrate an angular precision of 0.052º (about 1/10 of the solar disk diameter) during research drives and verify this tracking precision from measurements of the center to limb darkening (CLD, the changing appearance of Fraunhofer lines) in the mobile direct sun DOAS spectra.
