8 GRIB for historical and forecast weather data GRIdded Binary Compressed binary format Standard defined by WMO (World Meteorological Organization) Used to store weather data Based on rectangular grid Geographic coordinates as grid points 7 Copyright 2014 FUJITSU
9 Challenges and objectives Challenges Time series of global weather maps do not give immediate insight for certain location Difficult and long-lasting evaluation (e.g. for wind probability estimation) Late decisions Objectives Retrieve time series for certain location Create puncture for relevant grid points over relevant period of time Data transformation needed How many files and which data volumes? 8 Copyright 2014 FUJITSU
10 File quantities and data volumes 1 GRIB file per snapshot 4 snapshots per day 51,100 input files (timerelated) over 35 years 360 degrees of longitude 180 degrees of latitude 4 grid points per degree of longitude and latitude Add 1 grid point (north and south pole) 360 x 4 x (180 x 4 +1) = 1,038,240 grid points = output files (location-related) 128 meteorological indicators, 4 bytes each 25 TB of historical weather data Which solution concept will help? 9 Copyright 2014 FUJITSU
11 Client Distributed Parallel Processing Concept Slaves DFS Distribute data and I/O to server cluster nodes Local server storage Move computing to where data resides Shared nothing architecture Data replication to several nodes Master JobTracker TaskTracker DataNode TaskTracker Benefits NameNode DataNode High performance, fast results Unlimited scalability Fault-tolerance Cost-effective (standard servers with OSS) TaskTracker DataNode De-facto standard 10 Copyright 2014 FUJITSU
12 platform meets the challenges ECMWF data as input Load ECMWF data into HDFS Use MR to invert data From time series of world-wide weather maps Into grid point based time series of weather data Arrange as (sorted) KV pairs Key = grid point and time combined Value = Meteorological data Java apps Retrieve proximate time series, determine local weather development Visualize results Incremental update by short MR jobs Import weather history Retrieve proximate time series, determine local weather development Visualize result Invert time series 11 Copyright 2014 FUJITSU
13 Example: Wind park planning Time period: 14 years ( ) 4 snapshots per day 20,456 input files (timerelated) from ECMWF 21,221,625,600 records 1,038,240 grid points = output files (locationrelated) 12 Copyright 2014 FUJITSU
14 Solution approach effects time to value PERL ~100 min for processing data from 1 month 12 x 14 x 100 min ~ 12 days (over 14 years) 12 x 35 x 100 min ~ 30 days (over 35 years) Not acceptable in practice 13 Copyright 2014 FUJITSU
15 Solution approach effects time to value PERL ~100 min for processing data from 1 month 12 x 14 x 100 min ~ 12 days (over 14 years) 12 x 35 x 100 min ~ 30 days (over 35 years) Not acceptable in practice MapReduce 30 min for import to HDFS 141 min processing time Read HDFS files (historical data) Data transformation Write results to HDFS files ~120 x faster than script approach 8 Slave Nodes (2-socket, 6C/12T) Servers not fully utilized Potential for improvement by removing other workload Speed advantage by parallelization. 14 Copyright 2014 FUJITSU

17 In-memory platform as option For single users Hadoop platform is sufficient Retrieval and visualization within seconds Increasing response times Increasing number of users Increasing number of queries Complex queries, e.g. where in certain geographic area are most favorite locations for certain plans Solution: IMDG Accelerate retrieval and visualization Pre-defined queries memory-resident Import weather history Retrieve proximate time series, determine local weather development Visualize result Invert time series In-memory platforms help cope with any level of complexity. 16 Copyright 2014 FUJITSU
18 Data transformation Just 1x or more often? Depending on use case no one-time act New inversion of weather maps with new questions Deduction from meteorological indicators in global weather maps Example: Max. wind speed Peak speeds of crossing weather front occur only shortly at one location Often fail at 6 hrs grid Determine front on weather map timely before and thereafter What is the effort to realize new questions? 17 Copyright 2014 FUJITSU
19 Dreamlike Big Data Display weather data as table Spreadsheet like Excel Apply meteorological formulas directly to sample data Check partial results at once in spreadsheet Fast test run on significant (filtered) test data set Simple expansion to total data set and visualization Process large data volumes, but avoid programming MR jobs? Big Data for business users. 18 Copyright 2014 FUJITSU

21 Is this a Big Data project? Volume Variety Versatility Velocity Value 1 data source Structured data Data is not generated at high speed Analysis not always time-critical 25 TB x 2 is a considerable volume Traditional technologies do not help Big Data technologies solve customer problem Affordable Scalable with growth Expected processing time can be controlled Indeed no day-to-day Big Data project, but a very interesting one. 20 Copyright 2014 FUJITSU
