IMAPP AMSR-E Level 1 2Status

• The DB level 1 implementation successfully
  matches the standard products of brightness
  temperatures in terms of bias, RMS errors and
  correlation coefficients, i.e., the DB level 1
  data are well calibrated and geo-located and are
  ready for retrieval for geophysical products.
•  
• The AMSR-E level 2 products for precipitation and
  soil moisture are currently under evaluation.
  Those products will be compared with and
  validated against the official products.
