Python3 Script For Getting USHCN Monthly Temperatures

This script gives easy access to USHCN monthly raw, TOBS and Final adjusted temperatures.

Getting the data:
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tavg.latest.FLs.52j.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tavg.latest.tob.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tavg.latest.raw.tar.gz
tar xzvf ushcn.tavg.latest.FLs.52j.tar.gz
tar xzvf ushcn.tavg.latest.tob.tar.gz
tar xzvf ushcn.tavg.latest.raw.tar.gz

wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmax.latest.FLs.52j.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmax.latest.tob.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmax.latest.raw.tar.gz
wget http://cdiac.ornl.gov/ftp/ushcn_daily/ushcn-stations.txt
tar xzvf ushcn.tmax.latest.FLs.52j.tar.gz
tar xzvf ushcn.tmax.latest.tob.tar.gz
tar xzvf ushcn.tmax.latest.raw.tar.gz

wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmin.latest.FLs.52j.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmin.latest.tob.tar.gz
wget ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tmin.latest.raw.tar.gz
tar xzvf ushcn.tmin.latest.FLs.52j.tar.gz
tar xzvf ushcn.tmin.latest.tob.tar.gz
tar xzvf ushcn.tmin.latest.raw.tar.gz

Then cd into the new directory, which will have a new name every day. It will be something like ushcn.v2.5.5.20191004

Example usage:
python3 date.py USH00412679 7 1921 “EAGLE PASS”

Data for July, 1921 at Eagle Pass, Texas.

output:
Raw EAGLE PASS USH00412679 7 1921 37.29 99.12
TOBS EAGLE PASS USH00412679 7 1921 37.16 98.89
Final EAGLE PASS USH00412679 7 1921 35.92 96.66

Last two numbers in each line are Degrees C and Degrees F

You will have to know the station ID of the station you are looking for:
ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn-v2.5-stations.txt
