The data is available in two formats (tiled or native MM5 binary formats) and in the following three packages:
  • Individual Tiles
  • Regional Tile Groups - Country based groupings of tiled data
  • Full Domain
    • In either tiled format for use with CALPUFF modeling system
    • Or native binary format for use with models such as CMAQ.

Available Data Storage

Individual tiles or the Regional Tile Groupings are available on either DVD or USB hard drive. The Full Domain dataset is provided on a hard drive only. Be sure to specify the hard drive format on the order form and include the fee if requesting the data on a hard drive. 

External USB Hard Drive

Hard drives provided are USB 2.0 external drives of at least 320 GB capacity up to 2000 GB. The power supply can handle voltage in the range of 100-240V, 50-60Hz but contain a USA-type of electric plug that will require an adapter in other countries (not provided). User-supplied hard drives can be accommodated as a special order. Smaller drives (320 GB) do not require a power supply as these run on USB connection.

DVD Orders

MM5 data will be provided on DVDs, except for the Full Domain, which are available only on hard drives due to the large space requirements of the files

Pricing Notes

Note that for larger areas it is more cost-effective to purchase either complete Regions or the Full Domain, while for smaller areas (120 km x 120 km) it may be more cost-effective to purchase Individual Tiles. For example, in the Full Domain option the cost per tile decreases to ~US$15 per tile, compared to a cost of US $200 per tile if purchased as Individual Tiles.

Tiles can be added at later times to cover larger areas. The extraction software provided with the tiles combines tiles into a single 3D.DAT file. Each tile contains one year of 3-D MM5 data for an area covering 120 km x 120 km.

Software

Easy-to-use software is provided with the tiles to uncompress the data and create a CALMET-compatible 3D.DAT file. Any rectangular set of tiles can be combined into a 3D.DAT file for input into CALMET. The user selects a range in terms of latitude/longitude or MM5 grid points to be extracted and a time period and the extraction software will identify the tiles needed and perform the data extraction. New tiles can be added to existing tiles to allow the capability to create larger domains in the 3D.DAT files.
