Most issues carried out about building integrated photovoltaic (PV) system performance show average losses of 20%-25% in electricity production. The causes are varied, e.g., mismatching losses, partial shadows, variations current-voltage (I-V) characteristics PV modules due to manufacturing processes, differences the orientations and inclinations solar surfaces, temperature effects. These can be decreased by means suitable electronics. This paper presents intelligent module concept, a...
We present a one-dimensional model of the formation and viscous evolution protoplanetary disks. The early disk is modeled as result gravitational collapse an isothermal molecular cloud. disk's integrated according to two parameterizations turbulence: classical α representation β parameterization, representative non-linear turbulence driven by keplerian shear. apply DM Tau GM Aur, T-Tauri stars with relatively well-characterized disks, retrieving their surface density time. perform systematic...
Despite the importance of sand and dust to Mars geomorphology, weather, exploration, processes that move raise maintain Mars' ubiquitous haze produce storms have not been well quantified in situ, with missions lacking either necessary sensors or a sufficiently active aeolian environment. Perseverance rover's novel environmental Jezero crater's dusty environment remedy this. In Perseverance's first 216 sols, four convective vortices raised locally, while, on average, passed rover daily, over...
Abstract Rovers and landers on Mars have experienced local, regional, planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive. Over 5–11 January 2022 (L S 153°–156°), a storm passed over the Perseverance rover site. Peak visible optical depth was ∼2, visibility across crater briefly reduced. Pressure amplitudes temperatures responded to storm. Winds up 20 m s −1 rotated around site before wind sensor damaged. The imaged 21 dust‐lifting...
Abstract NASA’s Perseverance rover’s Mars Environmental Dynamics Analyzer is collecting data at Jezero crater, characterizing the physical processes in lowest layer of Martian atmosphere. Here we present measurements from instrument’s first 250 sols operation, revealing a spatially and temporally variable meteorology Jezero. We find that temperature four heights capture response atmospheric surface to multiple phenomena. observe transition stable night-time thermal inversion daytime, highly...
Abstract The Mars Environmental Dynamics Analyzer (MEDA) on board Perseverance includes first‐of‐its‐kind sensors measuring the incident and reflected solar flux, downwelling atmospheric IR upwelling flux emitted by surface. We use these measurements for first 350 sols of 2020 mission (L s ∼ 6°–174° in Martian Year 36) to determine surface radiative budget calculate broadband albedo (0.3–3 μm) as a function illumination viewing geometry. Together with MEDA ground temperature, we thermal...
Abstract The Mars Environmental Dynamics Analyzer instrument on 2020 has five Atmospheric Temperature Sensors at two altitudes (0.84 and 1.45 m) plus a Thermal InfraRed Sensor that measures temperatures the surface ∼40 m. We analyze measurements from these sensors to describe evolution of in Jezero up mission sol 400 (solar longitude L S = 13°–203°). diurnal thermal cycle is characterized by daytime convective period nocturnal stable atmosphere with variable inversion. find linear...
It has been proposed that the enrichment in noble gases found by Galileo Jupiter's atmosphere can be explained their delivery inside cold planetesimals. We propose instead this is a sign planet formed chemically evolved disk and were acquired mostly gaseous form during planet's envelope capture phase. show combined settling of grains to midplane outer layers, condensation onto these at temperatures below 20-30K, evaporation from high altitudes effectively lead progressive, moderate disk. The...
We present zonal and meridional wind measurements at three altitude levels within the cloud layers of Venus from tracking using images taken with VIRTIS instrument on board Express. At low latitudes, winds in Southern hemisphere are nearly constant latitude westward velocities 105 ms −1 cloud‐tops (altitude ∼ 66 km) 60–70 cloud‐base 47 km). high speeds decrease linearly no detectable vertical shear (values lower than 15 ), indicating possibility a vertically coherent vortex structure....
Saturn's slow seasonal evolution was disrupted in 2010-2011 by the eruption of a bright storm its northern spring hemisphere. Thermal infrared spectroscopy showed that within month, resulting planetary-scale disturbance had generated intense perturbations atmospheric temperatures, winds, and composition between 20° 50°N over an entire hemisphere (140,000 kilometers). The tropospheric cell produced effects penetrated hundreds kilometers into stratosphere (to 1-millibar region). Stratospheric...
