A c q u i s i t i o n   o f   o b s e r v a t i o n s

• Originally  developed   for  transmitting  real-­‐time  data  to  remote  machines

• Adapted  to  acquire  data  in  real-­‐time

• Highly  configurable

• Browser-­‐based  user  interface

• Multiple   simultaneous   transfers

• Monitored  by  24/7  shift  staff

• Analyst  call-­‐out  when  necessary

ECMWF  Product  Dissemination  System  (ECPDS)

S c a l a b l e   A c q u i s i t i o n   a n d   P r e -­‐ P r o c e s s i n g  ( S A P P )

• Observations  pushed   to  SAPP  from  ECPDS

• Decode  the  various  data  formats  (e.g.  BUFR,  GRIB,  HDF,  NetCDF)

• Apply   initial  quality  control

• Convert  to  a  consolidated   format  before  delivering   to  data  assimilation

• Monitored  by  24/7  shift  staff

• Analyst  call-­‐out  when  necessary

AtmosphereMonitoring • Acquire  specific  re-­‐processed  

satellite  data  sets  covering  the  period  2003  – present

• Use  an  offline  instance  of  SAPP  to  process  observations  for  reanalysis
