Figure5_data Folders in this directory include: Figure5a_data ascii files containing lat/lon coordinates of the cloud outlines illustrated in Figure 5a. Figure5c_model_results: Ash3d model input and output used to generate Figure 5c Figure5d_model_results: Ash3d model input and output used to generate Figure 5d Model simulation output from a magnitude 7 eruption: the distal Mazama tephra This data release contains model input and output for 57 simulations of tephra dispersal during the 7.8 ka Mazama eruption. Data were generated during in preparation of the following paper: Buckland HM, Mastin L, Engwell S, Cashman K (2022 (in pess)) Modelling the transport and deposition of ash following a Magnitude 7 eruption: the distal Mazama tephra. Bull Volcanol. 84(9):87. https://doi.org/10.1007/s00445-022-01593-1 Tags: Cascade Range, Cascade range, Mazama eruption, USGS Science Data Catalog (SDC), biota, All tags... explosive eruptions, explosive volcanism, none, tephra, Fewer tags Figure5d_model_results Files in this folder include: ash3d_input.inp The input file used in the Ash3d simulation that produced Figure 2c. Format of the input is as described in Mastin et al. (2013). CloudLoad_hhh.hhhrs.dat A series of files, in ESRI ASCII format, containing the cloud mass load at different times in the simulation, indicated by "hhh.hh" in the filename, where "hhh.hh" are the decimal number of hours since the eruption start. These are gridded data of cloud mass load in g/m2. Header lines in the file indicate the: (1) number of rows, (2) number of columns, (3) longitude of the lower left corner (i.e. the cell center of the lower left cell), (4) latitude of the lower left corner, (5) the cell spacing in dx... Figure6d_model_results Files in this folder include: phase1 and phase2: directories containing input and output for the two simulations that were combined (from phase 1 and phase 2 of the eruption) to generate the deposit file displayed in Fig. 6d. DepositFile_ESRI_ASCII.txt A gridded file in ESRI ASCII format, containing the mass load in kg/m2 throughout the model domain from the combined phase-1 and phase2 eruptions. Header lines in the file indicate the (1) number of rows, (2) number of columns, (3) longitude of the lower left corner (i.e. the cell center of the lower left cell), (4) latitude of the lower left corner, (5) the cell spacing in dx and dy respectively, and (6) the no-data value. Data are written in 10f10.3... phase1 Files in this folder include: ash3d_input.inp The input file used in the Ash3d simulation that produced the phhase-1 deposit used in Figure 6b. Format of the input is as described in Mastin et al. (2013). DepositFile_ESRI_ASCII.txt A gridded file in ESRI ASCII format, containing the deposit mass load in kg/m2 throughout the model domain. Header lines in the file indicate the (1) number of rows, (2) number of columns, (3) longitude of the lower left corner (i.e. the cell center of the lower left cell), (4) latitude of the lower left corner, (5) the cell spacing in dx and dy respectively, and (6) the no-data value. Data are written in 10f10.3 format, meaning that there are ten numbers per line, each... Figure2c_model_results Files in this folder include: ash3d_input.inp The input file used in the Ash3d simulation that produced Figure 2c. Format of the input is as described in Mastin et al. (2013). cloud_load_amimation.gif Animated gif file of cloud movement in this simulation. CloudLoad_hhh.hhhrs.dat A series of files, in ESRI ASCII format, containing the cloud mass load at different times in the simulation, indicated by "hhh.hh" in the filename, where "hhh.hh" are the decimal number of hours since the eruption start. These are gridded data of cloud mass load in g/m2.
