MODIS ASCII Subset Products - FTP Access
All of the MODIS ASCII Subsets are available from the ORNL DAAC's ftp site.
The directory structure of the ftp site is based on the abbreviated names for the MODIS Products. Terra MODIS products are abbreviated "MOD", Aqua MODIS products are abbreviated "MYD" and combined Terra and Aqua MODIS products are abbreviated "MCD". The abbreviated names also include the version number (also known as collection).
For specific products, please refer to the following table:
| Product | Acronym | Spatial Resolution | Temporal Frequency | Terra V004 SIN | Terra V004.8 SIN | Terra V005 SIN | Aqua V004 SIN | Aqua V005 SIN | Terra/Aqua Combined V004 SIN | Terra/Aqua Combined V005 SIN |
