      abstract     = {In this paper we present novel automated field spectroscopy
                      systems for collecting unattended, continuous and long-term
                      measurements of plant canopies and, more in general, of
                      Earth's ecosystems. These systems simultaneously collect
                      high and ultra-high resolution spectra in the visible to
                      near-infrared (VNIR) domain employing two spectrometers: i)
                      the first covers the spectral range 400–1000 nm with a 1.0
                      nm spectral resolution; ii) the second provides a
                      sub-nanometer spectral resolution within the 700–800 nm
                      spectral range. The data collected by the first spectrometer
                      allow retrieval of VNIR reflectance, while the higher
                      spectral resolution data from the second device permit
                      estimation of vegetation Sun-Induced Fluorescence (SIF) in
                      the O2–A band. The instruments are constructed by
                      assembling commercial and on-the-shelf optoelectronic
                      devices to facilitate reproduction of the instrument for
                      promoting measurements over different ecosystems. The
                      instrument's optical design, data collection and processing,
                      laboratory and in-field calibration methods are reported and
                      discussed. The high spectral resolution and the rigorous
                      calibration methods enable accurate estimation of SIF in
                      physical units by exploiting almost the same retrieval
                      concept as that of the European Space Agency FLuorescence
                      EXplorer mission. The instruments have been operated in
                      several field campaigns with the aim to show: i) the
                      possibility of continuous and seasonal monitoring of plant
                      growth and activity of an agricultural crop; and ii) the
                      diverse and specific daily course patterns of different
                      types of canopy. The datasets of canopy reflectance,
                      vegetation indices and SIF collected are shown and
                      discussed.},
