Project: Climate and FPI data for the National Inventory Report (Lead Chief Investigator)

Fund provider: Department of Industry, Science, Energy and Resources

Delivery: Spatially interpolated, 1 km resolution, climate and forest productivity data for land sector modelling work using the Full Carbon Accounting Model

Background: Gridded national climate and Forest Productivity Index (FPI) data are essential inputs to Australian Full Carbon Accounting Model (FullCAM) which is used to produce annual totals for Australia’s National Inventory Reports in the Department of Industry, Science, Energy and Resources (DISER) (formerly Department of the Environment and Energy). The reports are submitted to the United Nations Framework Convention on Climate Change (UNFCCC) each year to fulfil Australia’s international greenhouse gas inventory reporting commitments as a party to UNFCCC, the Kyoto Protocol and the Paris Agreement.

Fenner School of ANU has been providing high quality products of Climate and FPI to the Department since the inception of national carbon accounting system during the early 2000s. In particular, the ANUSPLIN package built by Fenner School (Hutchinson and Xu), a unique and world leading software to interpolate and build gridded climate surfaces from station recorded climate data, has made Fenner School at a very strong and unique position to provide accurate and reliable high resolution national gridded monthly and daily climate data to FullCAM modelling.

Significant innovations have been introduced by Dr Tingbao Xu to improve the quality of FPI products since 2017, which have significantly improved the quality and accuracy of outputs from FullCAM carbon modelling. These innovations include:

  1. Introduced serial national monthly NDVI data with improved quality and spatial continuity to improve the sensitivity of FPI to environmental drives and to substantially uplift the accuracy of national FPI products.
  2. Constructed new national soil property data layers for FPI modelling from latest gridded national soil data developed by CSIRO, which significantly improved the spatial consistency and accuracy of FPI and Top Soil Moisture Deficit (TSMD) products.
  3. A streamlined computation has been introduced and built for producing FPI and TSMD products, and implementing primary quality assurance. That has resulted in much higher computing efficiency and elimination of human errors, which has effectively enabled the Department to reproduce serial FPI and TSMD products back to 1970. Most importantly, the computation automation has made reproduction of serial FPI and TSMD products feasible in the case such as model upgrading in FullCAM.

This project delivers also the daily climate statistics for crop and grass areas in ABS Statistical Areas Level 2 (SA2) regions. This task is to extract the areal average values of major daily climates (rainfall, mean temperature and pan evaporation, generated using ANUSPLIN from BoM’s stational records) for areas delineated by high resolution crop or grass masks in each ABS Statistical Areas Level 2 (SA2) region.

 

Project: Improved NDVI data for the National Inventory Report (Lead Chief Investigator)

Fund provider: Department of Industry, Science, Energy and Resources

Delivery: Calibrated and processed MODIS/Terra 1km monthly and annual NDVI national layers for producing consistent FPI products

Background: Normalized Difference Vegetation Index (NDVI) derived from remote sensing data has been the basic index for measuring the “greenness” of the earth’s surface over past decades. It is a popular and robust measure of vegetation activity at the land surface, and is widely used to study the spatial and temporal patterns of vegetation cover at various scales with the objective to understand the role of terrestrial vegetation in regional and global processes, such as global carbon and nitrogen cycle, global hydrological cycle and global energy cycle.

Monthly national NDVI is an essential input to FPI computation. It is used for producing LAI (Leaf Area Index), subsequently the APAR (Absorbed Photosynthetically Active Radiation) and I (Rainfall Intercept) data layers. NDVI is a robust and relatively “direct” measure of vegetation activity at the land surface. It is a materialized dynamic driving component in FPI model. Its value possesses a substantial leverage to producing a not-overly-rainfall-driven FPI value. A high-quality serial monthly NDVI data can play a constructive role in promoting the accuracy and robustness of sequential FPI product, and boosting the practical applications of FPI products.

NOAA/AVHRR NDVI data have been used in previous FPI products. Troubled by persistent system noises, random noises and sensor downgrading issues, NOAA/AVHRR NDVI data has been deteriorated and gradually replaced by MODIS/NDVI products worldwide. However, a proper calibration is essential to utilize MODIS NDVI to replace AVHRR NDVI data for generating consistent FPI products to ensure the continuity of FPI project. An extensive effort has been taken in a review study to investigate and assess NDVI/LAI data sources from MODIS and other satellite platforms, and the relation between AVHRR/NDVI and MODIS/NDVI. The following processes are proposed.
