The following images compare 3 years (1998-2000) of TRMM version 5 and version 6 rain products calculated from the standard 3G68 products (available at ftp://trmmopen.gsfc.nasa.gov/) at 0.5° lat/lon resolution.

PR v5 vs. v6

• Unconditional Rain Rate (mm/d)
• Conditional Rain Rate (mm/h)

TMI v5 vs. v6

• Unconditional Rain Rate (mm/d)
• Conditional Rain Rate (mm/h)

PR v5 vs. TMI v5

• Unconditional Rain Rate (mm/d)
• Unconditional Rain Rate (mm/d), smoothed with a 1:2:1 filter to temper sampling uncertainty
• Conditional Rain Rate (mm/h)

PR v6 vs. TMI v6

• Unconditional Rain Rate (mm/d)
• Unconditional Rain Rate (mm/d), smoothed with a 1:2:1 filter to temper sampling uncertainty
• Conditional Rain Rate (mm/h)
