Abstract In Part 2 of this two‐part paper, documentation is provided key aspects a version the AM4.0/LM4.0 atmosphere/land model that will serve as base for new set climate and Earth system models (CM4 ESM4) under development at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL). The quality simulation in AMIP (Atmospheric Model Intercomparison Project) mode has been 1. provides components some sensitivities to choices formulation values parameters, highlighting convection parameterization...
Abstract In this two‐part paper, a description is provided of version the AM4.0/LM4.0 atmosphere/land model that will serve as base for new set climate and Earth system models (CM4 ESM4) under development at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL). This version, with roughly 100 km horizontal resolution 33 levels in vertical, contains an aerosol generates fields from emissions “light” chemistry mechanism designed to support but prescribed ozone. Part 1, quality simulation AMIP...
Abstract We analyze and compare atmospheric temperature data from three landed missions: Mars Science Laboratory (MSL) Curiosity rover, Phoenix lander, Pathfinder lander. were lander missions that operated for 84 151 sols, respectively. MSL is a rover operates on the surface of Mars. It has recorded air more than five Years (MY). denoise detrend each mission use those results to calculate variance in as diagnostic variability at surface. The show consistent seasonal pattern with little...
Abstract. A community diagnostics and performance metrics tool for the evaluation of Earth System Models (ESMs) has been developed that allows routine comparison single or multiple models, either against predecessor versions observations. The priority effort so far to target specific scientific themes focusing on selected Essential Climate Variables (ECVs), a range known systematic biases common ESMs, such as coupled tropical climate variability, monsoons, Southern Ocean processes,...
Abstract Surface pressure measurements on Mars have revealed a wide variety of atmospheric phenomena. The Science Laboratory Rover Environmental Monitoring Station sensor data set is now the longest duration record surface Mars. We use first 2580 Martian sols, nearly 4 years, to identify waves with periods tens minutes hours using wavelet analysis residual after tidal harmonics are removed. find these clear diurnal cycle strongest activity in early morning and late evening seasonal second...
Abstract We use near‐infrared spectra returned from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard Orbiter (MRO) to provide retrievals of column‐integrated optical depth water ice aerosols more than 5 Martian years between Year (MY) 28 at L s = 112° (27 September 2006) and MY 33 213° (30 August 2016). have developed a radiative transfer model this purpose that retrieves aerosol opacity feature near 3.3 μm using CRISM hyperspectral observations first time. The...
Abstract Martian dust lifting is believed to occur through two primary mechanisms: devils and wind stress forced lifting. Gale Crater's varied terrain meteorology provide a unique in situ perspective on lifting, with the Mars Science Laboratory Curiosity rover passing both conditions locations detrimental (e.g., crater floor) those active sand motion frequent Bagnold Dunes). Between L s = 248° Year 33 51° 37, over ∼3.5 years 2,300 sols, rover's Navigation Cameras took 1,260 dedicated image...

Abstract In this work, we aim to develop artificial neural network (ANN) techniques reproduce the retrieval results of physical quantities from spacecraft observations solar system bodies using radiative transfer methods. The particular application here is dust optical depth, water ice and surface temperature on Mars daytime obtained by Thermal Emission Spectrometer board Global Surveyor. Compared against traditional techniques, our ANN successfully recovered three observations. principal...
The Mars Global Surveyor (MGS) mission carried a spectrometer and bolometer as part of the Thermal Emission Spectrometer (TES) instrument package. While ceased operations in early Year (MY) 37 due to aging required neon lamp, bolometers continued operate for nearly full year. This time-period covered MY 27 dust storm season most 28 aphelion cloud belt season. TES consisted with two additional broadband visible (0.3-3.0 µm) infrared (5-100 µm). Observations were taken both...
