Climate Data
Data is subject to the highest levels of quality control
Is the basis of the official records of historical weather and climate for a country (legal quality data)
Climate data typically is observed over a 24-hour period (true max / min)
Current standard for weather risk transactions
Often expensive and difficult to obtain

Climate Data: Summary: Climate Data: Summary Facts
Each Meteorological Office has some digital archives of historical observations
Many countries are currently providing limited real-time observations on their web sites (no historical data archives available on the internet)
Reliable and accurate observations in a near-real time environment is available for a limited number of core stations
Feasibility / comments
Preliminary discussions with these Met Offices indicate that data can be made available for market use
We are not able to comment on the quality of the data, we are assuming moderate quality at best
Sourcing data will be somewhat time consuming (redistribution contracts) and costly
Cleaning techniques will play a major role in assuring the accuracy and completeness of time series
Settlement data (per the U.S. and Europe) will probably not be available

History

Settlement = may be a problem
Data solutions for risk management: Data solutions for risk management As with any region of the world we begin by looking at the two most widely used types of data and then we will consider other options
Climate Data
Synoptic Data
Synoptic data is often observed over a 12-hour period (12-hour max / 12-hour min)
Undergoes minimal amount of quality control (erroneous observations problematic)
Exchanged among National Meteorological Services to produce forecasts (ECMWF, GFS,…)
Easier Access to Data / less expensive
Lack of settlement data in the traditional sense
Other Solutions
Synoptic Data: : Synoptic Data: Synoptic data in Central America is observed using the following convention (all times in UTC)
Minimum temperatured = 0000d to 1200d
Maximum temperatured = 1200d to 0000d+1
Precipitationd = 1200d to 1200d+1
Missing and erroneous observations are extremely problematic
Precipitation, sometimes missing is denoted by “0.0”
“good” stations the are ones missing less than 20% of observations (good climate stations are ones missing less than 5% of data)
Settlement data is non-existent in its traditional form (Met Office edited data)
Synoptic Data: Feeds : Synoptic Data: Feeds GTS (Global Telecommunications System) transmitted Synoptic reports
An analysis of the past 3-months of archived reports finds that 18 stations have reliable data feeds (max, min, precipitation)
Summary:
Feeds are reasonable
Feeds are useless without historical data for pricing
Synoptic Data: Historical data availability : Synoptic Data: Historical data availability Archived Synoptic reports from the ISH (Integrated Surface Hourly dataset) / Global Summary of the Day database
Inventory (mid 1970s to present)
Total of 49 stations with historical data
Belize = 3
Costa Rica = 6
El Salvador = 5
Guatemala = 8
Honduras = 15
Nicaragua = 7
Panama = 5
Maximum Temperature: 13/49 are missing more than 50% of all observations
Minimum Temperature: 13/49 are missing more than 50% of all observations
Precipitation: 18/49 are missing more than 50% of all observations
Synoptic Data: History & Feeds : Synoptic Data: History & Feeds History without feeds = useless
Feeds without history = useless
The COMPLETE PACKAGE is available for 18 locations
Country Summary
Belize = 1
Costa Rica = 0
El Salvador = 0
Guatemala = 5
Honduras = 9
Nicaragua = 0
Panama = 3
Synoptic Data: Summary: Synoptic Data: Summary Facts
The GTS feeds appear to be reliable with reasonable amounts of missing data
The historical data is reasonable with stations missing on average 23% of observations
This solution is feasible for some countries and not others (Costa Rica, El Salvador, and Nicaragua have no data)
Feasibility / comments
The data cannot be cleaned – not enough surrounding stations for traditional methods
Without cleaning the risk exists for erroneous observations
There is no reliable source for settlement data
We would recommend using this data as-is only if desperate

Review / comments: Review / comments Climate data
Best historical data solution (after cleaning), feeds questionable, settlement data problematic
Difficulty sourcing data / cost
Synoptic data
Easiest solution for ‘reliable’ feeds, historical data ok at best, settlement data non existent
To be used as a last resort
Private networks / upgrade existing systems
Best solution for settlement data and feeds
Costly and time consuming
Synthetic historical data not preferable
Recommendations: Recommendations Scenario #1 (one-off trade, small transaction, limited data budget)
Consider initial pricing using historical synoptic data or climate data
Focus on stations that already report via Synoptic or web site
Carefully word contracts with regards to settlement
Scenario #2 (one-off trade, large transaction, moderate budget)
Focus on stations with archives of climate observations (source data and CLEAN data)
Focus on stations that already report via Synoptic or web site
Employ an independent 3rd party for certification of data for settlement
Scenario #3 (strategic business direction, multiple transactions, large budget)
Select regions of interest, review climate data availability (sourced data, CLEAN data, synthesize data)
Work with Met Office to upgrade existing hardware and communication systems (install stations)
Employ an independent 3rd party for certification of data for settlement
