The academy view

The Academy View

The National Research Council (NRC, 2004) defines a CDR as a time series of measurements of sufficient length, consistency, and continuity to determine climate variability and change.


Climate data records cdrs and their application

A CDR Provides Consistency& Continuity

Homogenization reduces artifacts imparted by observing systems,

facilitating meaningful comparisons in space and time

Operational weather and hazard productsare produced rapidly to potentially save life and property

New satellite launched

Vegetation Greenness Index

Climate Data Records (CDRs)provide long term product consistency through rigorous reprocessing with advanced algorithms, ancillary data and evolved instrument understanding.

Time (year)


Cdrs can support decision makers hypothetical p roblems for climate data and information

CDRs Can Support Decision MakersHypothetical problems for climate data and information

  • Climate Information Responding to User Needs (CIRUN) Roundtable Q&A*

    • Can we get consistent data series on average and extreme events (e.g., that disrupt business operations) so that current trends in climate can be established? [Want] to inter-comparison locations (state, city) and changes … through time.

  • Energy Utilities

    • What is the closest historical analog (duration, extent, severity) to the this year’s hot spell?

  • Local Governments and Planners

    • Are city and county water sources (wells, reservoirs) stable given climate change?

  • International Shipping

    • Can transport companies get a competitive advantage by investing now in ships for routes through the Northwest Passage?

  • Agribusiness

    • How could a company adjust its portfolio of producers, transporters and foreign investment due to climate?

  • Not hypothetical – received from constituent.

The academy and the private sector

The Academy and the Private Sector

Either/Or ? Both? Same?

The National Research Council (NRC, 2004) defines a CDR as a time series of measurements of sufficient length, consistency, and continuity to determine climate variability and change.

The CDR Program provides proven satellite-derived climate data and information records – including data sets, source codes and documentation – to allow decision-makers, policy-makers and scientists throughout society to make informed decisions and analyses involving future weather and climate.

Climate data records cdrs and their application

2012 drought depicted by Vegetation Index CDR (July 17)

  • CDRs Supporting Farming and Agribusiness

  • Example: historical context

  • 5 km resolution,“wall-to-wall” (globally)

  • Historical record from 1981- to current

  • Collatoral products

    • Surface Reflectance

    • Leaf Area Index (LAI)

    • FPAR (photosynthetically active radiation)

Cdr access for decision makers

CDR Access for Decision Makers

User Model Of Data Access

Traditional Large Volume Data Access

Current method of data access and delivery

Preferred method of same

Going from “drinking from the fire hose” to “sipping a cup of tea”

Reduce the data volume, filter what remains, and mix with relevant ecological data to produce a desired product.


Summary

Summary

  • CDR Program supports private sector applications

    • Interim Climate Data Records offer many advantagesover operational weather products

      • More complete in time and space

      • Consistency over multi-satellite period of record

        • Enables searches for historical analogs

      • “climate quality algorithms”

      • Better ancillary inputs

      • Better sensor functioning knowledge
