First plenary meeting on spectroscopy Virtual | 23 - 25 September 2020 Christian Omuto

1. Item 3 GLOSOLAN concept notes
By Christian Omuto, FAO-GSP

2. Concept Note Background:
Case for Global Spectral Calibration Library & Estimation Service
• Growing demand for infrared
spectroscopy in soil labs worldwide
• Spectral library challenges: variations
in reference data, spectral
measurements, variation in dates for
wet/dry (spectra) soil testing
• Global spectral calibration library
with consistent spectra and
reference data to provide calibration
service
Growth Infrared Spectroscopy - IRS

3. Towards country-driven harmonized global spectral library
Consistent MIR spectra
and reference soil data
library (KSSL)
Global soil spectral calibration library
Protocols, SOPs,
guidelines and policies
Capacity building and
resources mobilization

for consistency
• Countries volunteer representative national
benchmark soil samples to build the calibration
library

6. Global soil spectral library and estimation service
Objective 2: To develop soil property estimation service
• Develop and serve open-source GLOSOLAN
spectral calibration service based on MIR
• Support property estimation service using MIR
spectra
• Periodically update calibration stability and
identify areas for improvement
