The display and data file does NOT account for daylight savings time (ie. during the summer the archive will be one hour behind daylight savings time).
Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April. Time reverts to standard time at 2 a.m. on the last Sunday of October. In the U.S., each time zone switches at a different time.

The weather station is situated on the top of 2111 Bancroft Street in Downtown Berkeley.

It uses a Campbell Scientific datalogger CR10X, PC 208W software, National Instruments Bridgeview, and collects data real-time and at 15-minute, 60 minute, and 24-hour intervals.

DATA FILES

These are comma delimited data files.

To download them to your computer:

(windows - right-click the link, and choose "Save target as")

(Mac - right-click the link, and choose "Download link to disk")

To view the data:

Open the data file using a text-editor or speadsheet program. Either import the data as a delimited file using commas as a separator or replace the commas with your own delimiter. To separate the 24-hour data, search for interval = "200". Use the 24-hour header with the 24-hour data and the 15-60min header with the remainder of the data.

15-60 min header	15-min and 60-min interval header
24 hour header	24-hour interval header

The datalogger considers "1" to be January 1st and "365" to be December 31st. In leap years, 1 is added to all dates between 1 and 60. The total number of days in leap years is 366. When converting to Excel, subtract 1 from all days before day 60.
