Dataset Progress Status Ongoing - data is continually being updated
Data Update Frequency Irregular
Purpose In the late 1990s NCDC realized the need to host digital images of weather and climate records on the internet. As a result, EV2 was developed as a key system for providing access to the millions of original source data images in the NCDC archives. With its upload and index capability, EV2 also enables the continuation of NCDC's commitment to make more of its weather and climate data available online so that users across the world can view climate and weather records held in the NCDC archives.
Use Limitations
  • Controlled user access to the EV2 system

Lineage information for: dataset
Lineage Statement The vast majority of the digital image records available originate from the NCDC physical archives through the Climate Database Modernization Program (CDMP). These efforts produced over 50 million images from 2000-2011. Additional limited scanning activities at NCDC also contribute to the image repository. Partnerships with other NOAA line offices and international weather services have contributed to the broad and global nature of digitally imaged records available from the NCDC.
