Python to MATLAB json.load

Hello buddies, I need to download automatically from this interface:

http://mesonet.agron.iastate.edu/request/download.phtml?network=IA_ASOS

Here is the python script which probably does the job:

https://github.com/akrherz/iem/blob/master/scripts/asos/iem_scraper_example.py

I tried to translate it to MATLAB, but I cannot retrieve data from the URL, it just gives some info. Here the initial part of my code:

URL = 'http://mesonet.agron.iastate.edu/cgi-bin/request/asos.pydata=all&tz=Etc/UTC&format=comma&latlon=yes&year1=2012&month1=08&day1=01&year1=2012&month1=09&day1=01'; STATE = 'MN'; NETWROK = 'AWOS%s_ASOS%MN';

%get metadata---------------------------- uri = 'http://mesonet.agron.iastate.edu/geojson/network.php?network=%sAWOS.php';

%HEADER = http_createHeader('referer',uri) %DATA = urlread2(uri,'', '', HEADER) urlread(uri)

ans =

{"type":"FeatureCollection","crs":{"type":"EPSG","properties":{"code":4326,"coordinate_order":[1,0]}},"features":[]}

Any help is really appreciated. Thank you.
