Structures of carbon nanotubes covalently functionalized with charge-transfer groups.
This dataset contains 16 simulation cases which are driven by the same large-scale forcing and exposed to a rough surface. Members of the parametric set of simulations differ by stable density stratification, which is imposed via a Dirichlet boundary condition (viz. constant temperature difference between upper and lower domain boundary). The cases are labelled by their ID (N, S001,..., S128, ..., S256P) according to the stratification measured by the Richardson number Ri_Λ; N stands for neutral stratification, S for stable. The simulations were carried out sequentially in time starting from the neutral case N, a suffix P indicates three concurrent runs for very stable stratification (S128P, S192P, S256P). Here the bulk Richardson number Ri_B is evaluated based on the boundary layer thickness of the neutrally stratified case N such that it does not evolve over the course of simulation. The choice of Re_Λ = 5x10^5 corresponds to Re_D = 1000 (Re_D = DG/ν, with the laminar Ekman-layer depth D = (2ν/f)^0.5 ) and a friction Reynolds number Re_τ ≈ 2700 for the neutrally stratified case. Two computational grids are used: (A) 3840x704x3840, (B) 3840x576x3840 with similar spatial resolution of approximately 2.6x1.0x2.6 wall units and a domain size in terms of the Rossby radius of 0.27x0.26x0.27 for grid (A), and 0.27x0.11x0.27 for grid (B). This dataset contains a PDF file outlining the simulation setup and description of the variables contained in the netCDF files. A detailed description of the methodology and implementation is found in the git repository https://github.com/turbulencia/tlab, which contains the relevant code and a manual.

The pansharpening method used here is HSV color space conversion. The HRSC color processing is described in Michael et al. (2016). An overview of the HRSC processing methodology and product characteristics is described in Gwinner et al., 2016.

The results range from 1675 to 1815. The file records the search term, archive directory and code of the record, date of the record, kind of record, title, and availability online. It then records whether the record includes any remarks on the condition of weapons/artillery (as opposed to simply recording numbers), and if so whether problems are noted, whether those noted problems are related to decay or climate, and finally whether mention is specifically made of rust/oxidisation. This data is intended to support the RUSTEE project; specifically, research into how the claims made in travel narratives about the problems with rusting equipment in different climates (Ligon 1673, Ellis 1748) are or are not reflected in routine colonial administrative correspondance in France's equatorial American colonies. It should also be useful to researchers interested more generally in the role of the island environment, climate and weather in European colonial projects.

The mapping was done in ArcGIS 10.8.2 using CTX and HiRISE data (Planetary Data System Imaging Node https://pds-874 imaging.jpl.nasa.gov/) and HRSC data (data archives of ESA and NASA and https://maps.planet.fu-berlin.de [Walter et al., 2018]). For the minimum extent of the western delta a GIS version of the map of [Stack et al., 2020] was used. Details of mapping are described in [Ovchinnikova A. et al. A modeling approach for water and sediment transport in Jezero crater on Mars based on new geomorphological evidence. Icarus (accepted)].
