OPeNDAP (Open-source Project for a Network Data
Access Protocol)

• What the Opendap can do?
• Opendap handles transport, translation and
  subsetting of data. Opendap allows us to access
  remote data over the internet
• using familiar data analysis and visualization
  packages like GrADS, Matlab, Ferret, IDL,... as
  if the data were on your computer
• without worrying about data storage formats,
  translating them on-the-flight (including in
  ascii), if necessary
• accessing only the data of interest (extracting
  geographical area, time series...)

Contribution to AMY08

• APCC/CliPAS Hindcast Organize analysis of
  existing hindcast datasets through APCC/CliPAS
  project to (a) identify a range of suitable
  metrics relating to the AAM for application to
  the outputs, (b) assess the seasonal prediction
  skills and identify common weakness of the
  current dynamic prediction of Asian monsoon, (c)
  determine the predictability of Indian Ocean
  Dipole in collaboration with Indian Ocean Panel,
  and (d) study the role of the MJO in the onset of
  the (1997) El Niño with Pacific Ocean Panel.
• WCRP/TFSP Dataset Propose new hindcast
  experiments on the impact of land surface
  (experiment) initialization and land-atmosphere
  interaction on the Asian summer monsoon rainfall
  in the continental regions in collaboration with
  WGSIP and TFSP. Coordinated coupled model AAM
  intraseasonal prediction experiments (panel from
  the COPES TFSP Interactive Atmosphere-Ocean-Land-I
  ce Prediction Experiment).
• Data Depository for AMY08 (1) Observation data
  representative/super stations? selected set of
  variables for model verification?(2) Data
  assimilation/data integration project/Model
  experiments? (OPeNDAP will be useful here) (3)
  Compilation of data catalog (Metadata)
