TY - DATA AB - This raw data reflects readings from instruments mounted on or near a 82 meter meteorological tower located at the [National Wind Technology Center (NWTC)](http://www.nrel.gov/wind/ "NWTC website"), approximately 5 miles south of Boulder, CO (specifically: 39.9107 N, 105.2348 W, datum WGS84). The base elevation at the site is 1,855 meters AMSL. The dataset includes irrandiance information, such as global PSP (W/m2) and meteorological data, such as temperature, pressure, and wind speed and direction (at 2m, 5m, 10m, 20m, 50m, and 80m). Included here is a portion of the available data: from August 24, 2001 - March 10, 2011. A separate dataset is available for the period between [September 23, 1996 and August 23, 2001](http://en.openei.org/datasets/dataset/raw_data_from_national_wind_technology_center_m2_tower__1996_-_2001_ "Dataset within OpenEI, 1996 - 2001"). The [NWTC website](http://www.nrel.gov/midc/nwtc_m2/ "Website for M2 Tower data") provides up to the day updates to this data, from as early as August 24, 2001 through yesterday, as well as [instrument specifications](http://www.nrel.gov/midc/nwtc_m2/ "NWTC M2 Instrument Descriptions").
