Welcome to my repository for education and outreach code.  Below are details about code for tephigram plotting and global warming experiments.



# Tephigram Plotting

The tephiplt code allows users to plot the following isopleths as presented in tephigrams: temperature, potential temperature, wet bulb potential temperature, pressure and water mixing ratio.  To ensure dependecies are installed, the pip setup is recommended:



i) at the command line create a virtual environment in a suitable location (the environment will also contain the tephigram plotting package) using at least python 3: python3 -m venv tephi_env



ii) activate this virtual environment: source tephi_env/bin/activate



iii) ensure pip up to date in this environment: pip install --upgrade pip



iv) at the command line change to the site_packages directory of this environment (this is where the tephigram plotting package will be installed)



v) install the package: python -m pip install --upgrade tephiplt



You are now ready to run the package:



i) when sure of being inside the site_packages directory of the virtual environment, run code: python tephiplt

Raspberry Pi stuff:



Installing operating system:

Get pi connected to wifi via tethering to phone:

to set up the screen, connect to the internet using above and then follow instructions saved in GWworkshop as RPi_screen_instructions.pdf

How to shut down raspebrry pi:

From the command line or a terminal window you can enter the following to do a clean shutdown:

sudo shutdown -h now

Or from the LXDE GUI:

Click the shutdown button (red power button) in the menu bar at the bottom right corner of the screen. Then click shutdown (or logout on newer version, then issue the shutdown command listed above),

Once it says "system halted" you can remove the power cord if needed.

setting up a new pi with thermometer.py



tether phone with wifi on (https://www.youtube.com/watch?v=x_yhJ_QBfaU):



plug phone into usb port and turn on tether option and wifi



then in terminal: 

sudo dhclient usb0 



sudo apt-get update



set up the mod probe:

sudo nano /boot/config.txt 

at bottom:

# Enable thermometer

dtoverlay=w1-gpio

 

then restart pi:

sudo reboot



reconnect to smartphone:

select tether on phone, then in terminal:

sudo dhclient usb0



Create virtual environment: (http://raspberrypi-aa.github.io/session4/venv.html)



sudo pip3 install virtualenv

virtualenv GWwork --system-site-packages



cd GWwork

source bin/activate



sudo apt-get install tcl-dev tk-dev python-tk python3-tk fbi



python3 -m pip install numpy matplotlib



# check that matplotlib works:

python3 

import matplotlib.pyplot as plt



this tells us if it works.

To make it work, go to the matplotlib backend directory.  To find this do the following: 

sudo apt-get install locate

sudo updatedb

locate matplotlib

which indicates the location of the matplotlib directory,

then cd into the backend directory and open the __init__.py file, inisde here set the backend to ‘TkAgg’, in the latest attempt this was done by setting the name variable



save thermometer.py in GWwork

save a plot by adding (https://chartio.com/resources/tutorials/how-to-save-a-plot-to-a-file-using-matplotlib/)

plt.savefig(‘TEMP_timeseries.png')

to thermometer.py



view figure with (https://www.cpdforteachers.com/resources/view-images-on-your-raspberry-pi):

gpicview TEMP_timeseries.png



deactivate environment:

deactivate



pins: yellow - 4

red - 3v3

blue - GND



need good connection between ribbon and header

 having gold end of resistor on the 3v3 end works
