Microbarometer read/plot from Python

Easy Python program for reading and plotting SEED microbarometer data. Uses ObsPy.

Install

python -m pip install -e .

If you have trouble installing PROJ.4, try

conda install cartopy

Usage

import microbarometer as mb

data = mb.load('myfile.asc')

Data format

ObsPy is mostly for MiniSEED, and wasn't able to read the particular .seed files we had. An alternative method is to convert SEED to SAC format:

1. Download rdseed utility. The executable rdseed.rh6.linux_64 worked for me on Ubuntu as well.
2. extract executable. For Ubuntu:

   tar xf rdseedv*.tar.gz rdseedv*/rdseed.rh6.linux_64
   mv rdseedv*/rdseed* rdseed
   

3. convert SEED to SAC, for example to write SAC ASCII (readable by Pandas)

   ../rdseed -f myfile.seed -o 6 -d
   

Other output formats are possible via the -o option.

Notes

To get help:

./rdseed -h

channel BDO is "Bottom Pressure" in Pascals.

• Convert SEED to SAC (readable by ObsPy, MatSAC, etc.):

  ./rdseed -f myfile.seed -d
  

• List time range of data with -t option:

  ./rdseed -f myfile.seed -t
  

• Read SEED headers (extensive metadata):

  ./rdseed -f myfile.seed -s
