Ground-based monitoring plans

1
Ground-based monitoring plans

• NAFE workshop
• Melbourne, 10 February 2005

2
General

• Goulburn Catchment Campaign Nov. 2005
• Murrumbidgee Catchment Campaign Nov. 2006
• Campaigns are not planned as big integrated and
  highly structured campaigns (such HAPEX etc.)
  with unified themes.
• Campaigns are designed to give people access to
  airborne monitoring and ground-based monitoring
  data in return for contributing to ground-based
  monitoring programs.

Why link airborne and ground-based measurements?

• Airborne monitoring over experimental sites,
  contrasting sites/regions and along transects
• Same sites may be monitored on different days and
  at different times
• Need for close coordination between airborne and
  ground-based monitoring programs
• Ground-based observations/measurements aimed at
  validation of airborne observations, calibration
  of derived variables, or providing supplementary
  data

Walker, Kalma and Kim

• Project title
• Resolution monitoring of surface and root zone
  soil moisture
• Objectives
• Development and validation of passive microwave
  algorithms
• Downscaling of low resolution passive microwave
  soil moisture measurements
• Validation of derived root-zone soil moisture
  from the assimilation of near-surface measurements

5
Ground-based monitoring(Walker, Kalma and Kim
example)

• Long-term monitoring of soil moisture profiles
  and associated meteorological data
• Extensive ground-based measurements of
  near-surface soil moisture and soil temperature
  across individual farms during airborne
  monitoring campaigns.
• Each participant would be expected to sign up for
  at least 2 weeks and contribute 50 of their time
  to soil moisture monitoring program (i.e.
  mornings or afternoons)

6
Your monitoring requirements

• Soil moisture (Jeff Walker)
• Irrigation and salinity (Hector Malano)
• Runoff etc. (Brian Finlayson Mark Thyer)
• Evapotranspiration (Helen Cleugh)
• Carbon budgets (Greg Hancock)
• Forestry (Neil Sims)
• Vegetation dynamics (Patricia Saco)
• Bushfires (Ian Grant)
• Nutrients and water quality (Jim Wallace)
• Others

7
What measurements will be required in your
research?

• Intensive ground-based measurements (e.g. flux
  measurements)?
• Manual ground-based observations at specified
  times (e.g. biomass)?
• Continuous (unattended) monitoring (e.g. climate,
  streamflow, radiation balance)?
• Airborne monitoring requirements?

8
Where do you want to take your ground-based
measurements?

• Intensive measurements in selected small area?
• Extensive measurements over regions (catchments,
  farms etc.?
• Arrangement of transects?
• Sites, regions for airborne monitoring?

9
When do you want to take your ground-based
measurements?

• Temporal changes (between days?) repeated
  airborne monitoring
• Diurnal patterns (airborne monitoring throughout
  day?)
• Observations (days, hours) prior to flights
• Observations during flights
• Observations (days, hours) after flights
• Timing of flights

10
Discussion 1

• Summary/overview of desired measurements
• Are they all really needed?

11
Discussion 2

• How are we going to resource all those
  infrastructure demands?
• Minor modifications to monitoring plans
• Adding additional infrastructure
• Buying/borrowing additional equipment
• Planning additional manual measurements
• Increasing the number of staff and students
  participating in the campaign(s)

12
Other issues

• Data sharing
• Logistics
• Budgets
• Background data
• Data management
• Actions

13
Data sharing

• Reviewing interests and needs
• Data may be used by more than one user
• Agreement needed on site requirements
• Identifying common sites, regions
• Sharing in ground-monitoring programs
• Reconciling different demands (times, sites,
  repetition)

14
Logistics

• Equipment requirements
• Ground transportation
• Accommodation
• Need for Campaign Managers?
• Site access interaction with land owners
• Power requirements
• Publicity flyers?

15
Budgets

• Cost of flying
• Cost of data processing
• Cost of ground-based monitoring
• Equipment
• Ground-transportation
• Accommodation
• Insurance

16
Background data

• Maps and GIS
• Soils
• Vegetation and land use
• Terrain (DEM)
• Climate and hydrology data
• Other (archived) satellite data (Landsat etc.)

17
Data management

• Need for short written proposals on data
  requirements and how data will be used
• Restricted vs. unrestricted access to data
• Need for data manager?
• Data sharing and ownership IP issues
• Publications PhD students
• Website extending OzNet?

18
Actions

• Express interest in participating in campaign(s)
• Identify airborne and ground-based monitoring
  needs
• Write brief proposal on data interests and how
  data will be used
• Identify people taking responsibility for
  sub-areas
• Indicate availability to participate and
  preferred times
• Indicate how many people will take part (staff,
  students)
