Summary
Files in this folder include: ash3d_input.inp The input file used in the Ash3d simulation that produced the phhase-2 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 occupying 10 spaces, [...]
Summary
Files in this folder include:
ash3d_input.inp
The input file used in the Ash3d simulation that produced the phhase-2
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 occupying 10 spaces, with 3 digits to the right of the decimal place.
Each row of data in the model may occupy several rows in the output file.
