abstract = {The PRISMA satellite mission launched on March 22nd, 2019
is one of the latest spaceborne imaging spectroscopy mission
for Earth Observation. The PRISMA satellite comprises a
high-spectral resolution VNIR-SWIR imaging spectrometer and
a panchromatic camera. In summer 2019, first operations
during the commissioning phase were mainly devoted to
acquisitions in specific areas for evaluating instrument
functioning, in-flight performance, and mission data product
accuracy. A field and airborne campaign was carried out over
an agriculture area in Italy to collect in-situ multi-source
spectroscopy measurements at different scales simultaneously
with PRISMA. The spectral, radiometric and spatial
performance of PRISMA Level 1 Top-Of-Atmosphere radiance
(LTOA) product were analyzed. The in-situ surface
reflectance measurements over different landcovers were
propagated to LTOA using MODTRAN5 radiative transfer
simulations and compared with satellite observations.
Overall, this work offers a first quantitative evaluation
about the PRISMA mission performance and imaging
spectroscopy LTOA data product consistency. Our results show
that the spectral smile is less than 5 nm, the average
spectral resolution is 13 nm and 11 nm (VNIR and SWIR
respectively) and it varies ±2 nm across track. The
radiometric comparison between PRISMA and field/airborne
spectroscopy shows a difference lower than $5\%$ for NIR and
SWIR, whereas it is included in the $2–7\%$ range in the
VIS. The estimated instrument signal to noise ratio (SNR) is
≈400–500 in the NIR and part of the SWIR (<1300 nm),
lower SNR values were found at shorter (<700 nm) and longer
wavelengths (>1600 nm). The VNIR-to-SWIR spatial
co-registration error is below 8 m and the spatial
resolution is 37.11 m and 38.38 m for VNIR and SWIR
respectively. The results are in-line with the expectations
and mission requirements and indicate that acquired images
are suitable for further scientific applications. However,
this first assessment is based on data from a rural area and
this cannot be fully exhaustive. Further studies are needed
to confirm the performance for other land cover types like
snow, inland and coastal waters, deserts or urban areas.},
