Instance Specific Changes

A-Train

NEESPI

• URL: http://disc1.sci.gsfc.nasa.gov/daac-bin/G3/gui.cgi?instance_id=neespi
• Changes
  • This is the first operational release of NEESPI Giovanni.
• Caveats
  • In creating time series plots, the method used in the current version is a simple arithmetic mean which is different from the area weighting used in some other Giovanni instances.
  • In the scatter plot, all selected parameters need to have data over the selected time period. Otherwise, it will likely fail. For example, if Aerosol Optical Thickness from both MOD08_M3.004 and MYD08_M3.004 are selected and the selected time range is from May 2002 to August 2002, it will fail to generate an image since MYD08_M3.004 is only available starting in July 2002. This problem will be fixed in the next release.
