Data for 2017 and 2018


I would like to get half hourly solar irradiance data from locations near Norfolk, VA. In the past, I have gotten observations from the Norfolk International airport and the air base at Naval Station Norfolk for years up to 2016.

I would like to get observations for 2017 and 2018.

I am using the python script on the NREL web site to obtain the data. As a test, I tried to get data for 2015 (which worked) and 2016 (which failed with a bad URL error).

Is the half hourly irradiance data available for 2017? Is there a change in the URL for this year?

Through the data portal on the web site, I was able to get data for 2016 in a file named 1168555_36.93_-76.3_2016.csv.

A web search indicated that a file named 1168555_36.93_-76.3_2017.csv exists, but I was not able to find a link.

Thanks in advance for your help.

Hi, Could you suggest me as to how i get the data of 2015 and 2016?
