VIP Workshop - Introduction and Goals 1. More than 30 years of daily global AVHRR and MODIS data have

been processed to create seamless Earth Science Data Records (ESDR) of Vegetation Index and Land Surface Phenology parameters.

2. June 2012, the MEaSUREs VIP team made Version 2 of these data records available while planning the reprocessing of a new Version 3 (and now 4).

3. The workshop is organized into plenary, poster, and breakout discussion sessions aimed at bringing together the data producers and application and research users of these products.

4. The goals of this workshop are to introduce these ESDRs, their characteristics, limitations, and use in a variety of applications and research topics, and aims to solicit user feedback about these ESDR records.

5. The workshop will also explore the possibilities of starting and organizing a long term data product intercomparison effort aiming at producing one or more research manuscripts.

VIP Workshop Tucson, AZ - January 23-24, 2013

30 Years of VI and Phenology

Observations

Project Objectives

• Create a long term data record (30+ yrs, ‘81+)

• NDVI + Backward compatible EVI (EVI2) (Resistance to

background and atmosphere noise, no saturation over high biomass (High-C), strong correlation with canopy structure (Phenology), highly correlated with flux tower photosynthesis (GPP) in both tropical and temperate ecosystems at seasonal scales, widely and successfully used and adopted)

– Independent of sensor (Seamless) and focused on consistency

– Derive phenology metrics

Project Overview AVHRR record, ‘81 – ‘’99

‘98-’02 SPOT- VGT Data to

Bridge AVHRR & MODIS records

1981 -2013 sensor independent VI and Phen. ESDRs

Homogenous clusters map.

Areas with same characteristics

MODIS record, ‘00 – ’13

Data retention filter.

Only retain high quality data

VIP - ESDR

• Processing plans: V2,V3,V4

• EVI2 : Forward and backward compatibility with all sensors

• Spectral Transformation Equations to MODIS-equivalent

• Error and Uncertainty

• Documentation (e.g. ATBD)

• Archive and data distribution

3:30 Introduction to the Open Discussion Session (Wim Van Leeuwen, UA) Open discussion with focus on:

The MEASURES VIP product suite

Long term data records in general

Errors/uncertainty & Validation of VIs and LSP

Applications and Limitations

Feedback for Collection 4.0 reprocessing 4:30 Summary and Report back Two volunteer rapporteurs

4:45 Explore the potential for an “Intercomparison of Long Term Data Records” Exercise aiming to produce research manuscripts

5:00 PM Adjourn (Please remove posters) Possible group dinner at a local restaurant (TBD).

Feedback & Open Discussion Foci: (summary report – rapporteurs)

1. The MEASURES VIP product suite

2. Long term data records in general

1. Operational available?

2. Data format access

3. Filtering, gapfilling, interpolation/missing data

4. Quality flags, documentation, delta over time/versions…..

3. Errors/uncertainty & Validation of VIs and LSP

4. Applications and Limitations

5. Feedback for Collection 4.0 reprocessing – improve continuity possible with per pixel method, but expensive/possible headaches between MODIS C5 and C6/Five months of feedback on version 3.0

6. Temporally Seamless?

7. Daily vs 15-day comp. vs daily LAI ground based

8. 1km data availability for NA? - Data availability is an issue

9. Modernize algorithms/consensus – need to group up/VIP provides a common source

10. Need for global climate modelers
