Does anyone know of sources for downloadable global composite NDVI datasets (2-week to 1 month composites) that include more recent data than 2006? The GLCF (http://glcf.umiacs.umd.edu/data/gimms/) and USGS (http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/NDVI) composite AVHRR data is available through 2006, but in a cruel twist of fate, I need data for 2007. My area of interest is NW Siberia, so I don't necessarily need global coverage if anyone is aware of more geographically specific data. Thanks in advance.

This was very helpfull. But, I wonder if the data can be downloaded later, just log in later on MRTWEB? Directory wont expire? –  Filip May 2 at 18:57

The MODIS sensors aboard Terra and Aqua have vegetation indices data, including NDVI and EVI. The MODIS Products Table shows all the available data. For both Terra and Aqua, they have 16 day data at 250, 500, 1000, and 5600 meters and monthly data at 1000 and 5600 meters.

The easiest way to get MODIS data downloaded and projected into a useful coordinate system (the default is sinusoidal) is through the MRTWeb Tool. Here's a screenshot of it in action:

I've spent a lot of time using MODIS vegetation indices data and using the MRTWeb tool, so feel free to ask any followup questions.

I just spent a few minutes running through the interface, and this looks like a great resource, dmahr. I don't have a lot of time right now to spend on the site - does the download option open up once you have selected your processing parameters and processed the scenes? –  JWallace Mar 15 '12 at 16:33
    
@JWallace Yep, once the processing is complete it just gives you an FTP link to download. Keep in mind that MRTWeb is an online version of the MODIS Reprojection Tool (MRT). As you can imagine, the online version is finnicky and sometimes is down. If it's not working, just leave it and try again later. If it goes a long time without working, call the LP-DAAC help line at 605-594-6116. Brett Lien is the guy who administers MRTWeb, as of last year. –  dmahr Mar 15 '12 at 17:26
    
Thanks so much for the help dmahr. I'm going to leave this open for a little bit to see if anyone has any good leads on some other obscure Russian data sources, but I'll accept this because, well - it was exactly what I was looking for! –  JWallace Mar 15 '12 at 17:36
    
dmahr, great answer! Do you know if this tool can be used for MODIS MOD16 dataset also? –  Tomas Jul 19 '13 at 10:25
    
@Tomas I don't think MOD16 is in MRTWeb, but you may be able to use the regular MRT to reproject and mosaic MOD16 .hdf files that you've downloaded. –  dmahr Jul 19 '13 at 12:31
