bluedot

Blue-dot (disk-integrated Earth) simulator.

Requirements for Installation

• Python 3
• pyhdf or python-hdf4 (for instance, conda install -c conda-forge pyhdf)
• healpy
• libradtran 2 (also netcdf4)

Add your_install_directory/bluedot to your PYTHONPATH.

Some tips for install

For installing libradtran 2.0.2, first you need to install netcdf4 (I needed to put -fPIC option in CFLAGS and CPPFLAGS in Makefile). Also

sudo mkdir /usr/local/share/libRadtran/data/ic/yang2013

and make a soft link of libRadtran2.0.2/data to the directory upper to the working directory.

Remove ".sol" in ic/yang2013/Makefile

DATAFILE = $(wildcarf *.sol.cdf)

Also, libradtran2 uses python 2.7 but bluedot uses python 3. So, when installing, I switch to py27 using conda,

conda create -n py27 python=2.7 anaconda
source activate py27

Then, configure, make, make install in libRadtran.

Data

• ISCCP (cloud data)
• MODIS (albedo)

Download bluedot.data.tar.gz from http://secondearths.sakura.ne.jp/bluedot/bluedot.data.tar.gz Untar the file and put directory as bluedot/earth.

Download bluedot.data.tar.gz from http://secondearths.sakura.ne.jp/bluedot/librad.data.tar Untar the file and put directory as bluedot/data.

Making wrapgpc.so

• read_isccp.py is the python binding for IO of ISCCP/GPC files. To use it, compile fortran (90) files as In bluedot/bluedot directory, execute

make

Then, you'll find wrapgpc.so.

Samples

In bluedot/bluedot directory, you can try these ones.

• Generate a pickle file (setting file) for PlanetMovie

python makemovie.py -p 

• Make a snapshot

python makemovie.py -f test.pickle -i 1

• Plot a snapshot

python plotgeo.py -i 1

• Emulate (for debugging)

 python ../makeexe.py -f emulate.pickle -i 1 30 -n 1 -e
