5A Short History
- 1983 NASA began to explore the concept of a
polar-orbiting platform to complement a manned
polar-orbiting space station - Beginning as System Z, gained momentum with
NASAs proposed Global Habitability program - After Challenger disaster, polar space station
disappeared as did manned servicing requirement - System Z became EOS Earth Observing System
- Several instrument suites were developed
- Surface Imaging and Sounding Package (SISP)
included the Moderate Resolution Imaging
Spectrometer - MODIS soon split into 2 concepts
- MODIS-N focused primarily on land and atmosphere
sensing but included some ocean bands - MODIS-T (tilting) focused on ocean
- Because of budget constraints, MODIS-T vanished,
replaced by MODIS-N and EOS-Color (to follow
SeaWiFS) - Further budget reductions led to replacement of
EOS-Color by SIMBIOS
6Some Obscure Facts
- MODIS was always viewed as the keystone sensor
for EOS - Three pairs of MODII were planned initially to
provide a 15-year time series - NOAA was involved for much of the development of
EOS - Budget constraints and orbit incompatibilities
led to eventual decoupling of NASA and NOAA - NASA always expected that NOAA would eventually
assume responsibility for MODIS-like measurements

30Level 4 Productivity
- Ocean primary production data is available only
as binned or mapped Level 4 (i.e. L4) data. - Ocean Productivity outputs are averaged weekly or
yearly. Like the L3 data, the L4 data is
organized spatially as either 4km ISEAG gridded
bins or as maps using a Cylindrical Equidistant
Projection. The mapped data products are
available in a choice of 4km , 39km, or 1 degree
spatial resolutions. More than one model is used
for deriving these data products and some quality
statistics are available.
