SpecNet - Linking optical measurements with flux sampling around the world.


Current Announcements:

SpecNet Annual Meeting at AGU:

When: Wed, Dec 14, 2016, 5-7 pm
Where: San Francisco Marriott Marquis, Golden Gate C1

Scheduled Meeting Topics:

  1.   1)   EcoSIS – spectral database and related tools
  2.   2)   SpecNet-Decagon sensor network – emerging results & discussion

A detailed schedule will be provided at the meeting.

For those of you involved in the SpecNet-Decagon sensor network, we invite you to:

  a) present a short (5-10 min) summary of your findings, or
  b) send up to 5 PowerPoint slides to be part of a summary presentation.

 Topics to consider:

  1)   Seasonal patterns of NDVI, PRI, and CCI for your site - how do they relate to fluxes and pigments (where available)?
  2)   How do the sensor patterns compare to MODIS or independent optical (e.g. spectrometer) measurements?
  3)   How well did the cross-calibration work?
  4)   What are the results of multi-angle sampling?
  5)   What problems/issues have you encountered?

In our follow-up discussion, we will discuss and compare approaches to analyzing these new datasets.  We will also begin the process of planning a summary publication on the results of this study.  Currently, we envision this as a meta-analysis involving all sites contributing data.  Another goal will be to create an archived database of the results to facilitate public access and long-term access to the data.

SpecNet (http://specnet.info) is a non-profit collaborative organization, with opportunities for individual participation.

We look forward to seeing you at AGU!

EcoSIS (Ecosystem Spectral Information System) Town Hall Meeting
Monday, Dec 9, 12:30-1:30
Moscone West Room 2011

Ecosystem Spectral Information System (EcoSIS) is a new initiative to encourage the development and use of spectral data and metadata to address ecological questions. We will introduce the objectives of EcoSIS and encourage audience input on how best to develop a spectral data system with broad utility. If you are interested in spectral data, remote sensing, or ecological questions that can be addressed with optical sampling or remote sensing, we encourage you to attend this town hall.

Additionally, the following AGU sessions and side meetings may be of interest to the SpecNet community:

  1. Session B027 – Emerging Frontiers in Biogeosciences
  2. Session B058 - Remote Sensing of northern high-latitude terrestrial and aquatic ecosystems.
  3. Session B059 – Remote Sensing of Terrestrial Carbon Fluxes
  4. Session B060 – Remote Sensing of Vegetation for Monitoring Ecosystem Functioning
  5. Session B065 – Spectra as Proxies for Vegetation Function
  6. Session B062 – Scaling EcosystemObservations
  7. Session B069 – Understanding uncertainty in remotely sensed vegetation data products

EUROSPEC Conference: 6th to 8th November 2013 in Trento, Italy. 

Note: The Trento abstract deadline has been extended to: 25th of August.

The conference addressed issues in these areas:

  1. Continuous and episodical spectral measurements integrating energy and matter fluxes
  2. Spectroradiometer calibration and field measurements issues
  3. Cyber-infrastructure, spectral database platforms
  4. Upscaling carbon flux and biophysical measurements using UAV, airborne, satellite optical data
  5. Remote and proximal sensing of vegetation fluorescence

Conference proceedings will be related to an upcoming special issue in the journal Biogeosciences.

Call for Abstracts - B059. Remote Sensing of Terrestrial Carbon Fluxes

American Geophysical Union (AGU) 2013 Fall Meeting 9-13 December 2013 San Francisco, California

Abstracts can be submitted between June 17 and August 6.

Note that AGU now requires first author to be an AGU member.

You are invited to submit an abstract to the following session at this year's American Geophysical Union (AGU) Fall Meeting:

B059. Remote Sensing of Terrestrial Carbon Fluxes

This session focuses on remote sensing based approaches for estimating carbon fluxes from terrestrial ecosystems. Modeled carbon fluxes are characterized by large uncertainties resulting from inappropriate parameterizations of key parameters controlling photosynthesis and respiration. Remote sensing supplies spatially extensive information useful for constraining model simulations and for estimating carbon fluxes at a range of temporal and spatial scales. We encourage contributions on innovative uses of remote sensing information from surface, aircraft and satellites for quantifying carbon fluxes at multiple scales. We also encourage contributions focusing on the use of fluorescence and thermal measurements for determining carbon fluxes.

NCEAS Working Group (Sept 18-22, 2006) 
SpecNet is holding a Working Group meeting at NCEAS (National Center for Ecological Analysis & Synthesis) at Santa Barbara, CA, Sept 18-22. The primary focus of this meeting will be the informatics needs of SpecNet. A better definition of protocols and data and metadata standards will facilitate the SpecNet goals of cross-site integration, model development, and satellite validation. All SpecNet sites and participants are encouraged to submit samples of data and/or metadata for this meeting.
