The  Regional  Climate  Model  Evalua4on  System  (RCMES)  

•  Joint  collabora4on:    JPL/NASA,  UCLA  

•  Designed  to  facilitate  model  evalua4on  and  decision  making    

–  Provides  access  to  numerous  (NASA)  observa4on  datasets  (RCMED)  

–  Python-­‐based  built-­‐in  toolkit  (RCMET)  has  regridding  capabili4es  and  calculates  and  visualizes  several  common  metrics  (RMSE,  Bias)  

–  Connec4on  to  the  Earth  System  Grid  Federa4on  allowing  for  access  to  CORDEX  and  CMIP5  models.  

•  Ini4al  target:    CORDEX

Evalua4on  of  Cloud  Compu4ng  for  Storage  &  Applica4on  of  NASA  Observa4ons  

Challenge  –  Regional  climate  model  evalua4on  with  daily  temporal  

resolu4on  to  assess  representa4on  of  extreme  events.  –  More  voluminous,  requires  scalability  in  web  services,  system  

throughput,  and  also  elas4city  based  on  study  demands  Objec?ve  

–  Understand  and  evaluate  popular  cloud  compu4ng  technologies,  and  provide  a  framework  for  selec4ng  the  best  one  for  suppor4ng  Regional  Climate  Model  Evalua4on  System  (RCMES)  &  applica4ons  such  as  the  Na4onal  Climate  Assessment  and  IPCC’s  CORDEX  regional  model  evalua4ons.  

Results    –  Conducted  evalua4on  demonstra4ng  44  %  

avg  query  4me  speedup  of  PostGIS  over  MySQL    for    5  years  of  5  parameters  of  obs  data  in  RCMES  

–  Will  incorporate  into  RCMES  to  facilitate  NCA            and  CORDEX  regional  model  evalua4ons.
