QualitySpec Trek Report - ASD Goetz Instrument Support Program

August 02, 2017

Written By Leena Leppänen, Finnish Meteorological Institute, Arctic Research, Sodankylä, Finland. 2017 Winning Goetz Instrument Support Program Project Title: "Spectral reflectance of snow in Sodankylä, Finland" 

ASD's QualitySpec® Trek (QST) was used for reflectance measurements of natural snowpack in Sodankylä. A total of 163 spectrums were measured, including 6 test measurements in the beginning. Usually, measurements were made in Intensive Observation Area (IOA) where snow pit measurements are made weekly in addition to several automatic measurements of snow and meteorological properties (Figure 1).

 

Figure 1. IOA measurement field. Location of snow pit area is marked with red circle. Snow pits were made to the same area but different spot every measurement occasion. Snowpack is suspected to be homogenous in that area.

The manual snow pit measurements includes definition of layers and for each measurement of grain size and type, hardness and wetness, and density profile and specific surface area (SSA) profile with IceCube, snow depth and bulk snow water equivalent (SWE). Automatic snow measurements at the site are snow depth, SWE, snow temperature profile every 10 cm, and snowfall intensity with particle size. More information about snow pit measurements and snow conditions in Sodankylä can be found from Leppänen et al. 2016.

Vertical profiles from snowpack were measured with QST to research vertical variability of reflectance in snowpack (Figure 3a). Measurements were made approximately every 2-3 cm, and 4-5 cm in depth hoar layer where coarse grains existed. Snowpack surface was measured also from top (Figure 3b). Forest snow pit profiles were measured for research of horizontal spatial variability (Figures 2a, 2b).

ASD Will Be at IGARRS 2017 - Will you?

July 19, 2017

ASD will be joining other remote sensing and industry professionals July 23 – 28th at the 2017 IEEE International Geoscience and Remote Sensing Symposium in Fort Worth, Texas.

You are invited to stop by booth #42 to visit with Susan Parks and Don Campbell to see ASD’s instruments in action.  We’ll have the FieldSpec® HandHeld 2 and TerraSpec® Halo Mineral Identifier on hand to discuss why ground truthing with a spectrometer is the best method by far to get the most out of your imagery.  

We look forward to seeing you at booth #42 at the IGARSS Symposium! 

 

LabSpec® Applications Relevant for Many Industries - Part 2/2

July 12, 2017

ASD’s LabSpec® 4 laboratory analyzers are rapid-results analytical instrumentation that are ideal for precise spectral analysis of a wide range of materials - this is Part 2 of our blog on the many uses and applications of our LabSpec instrument! 

The LabSpec 4 laboratory analyzer , is used to verify raw materials and detect contaminants (for quality and purity, etc.) during production as well as post production.

Use of the LabSpec instrument, through its many and varied application uses, offers a value add to manufacturing and lab testing efforts by helping to cut down costs while increasing yields - it does this by creating no waste, no sample destruction and by its ability to measure multiple constituents in a single scan.

The ASD webinar series offers one complimentary webinar each month focusing on a different application use; the LabSpec instrument is our instrument of focus for the months of May-July.

ASD’s LabSpec® 4 laboratory analyzers are rapid-results analytical instrumentation that are ideal for precise spectral analysis of a wide range of materials. 

Analytical instrumentation, like the LabSpec 4 laboratory analyzer , is used to verify raw materials and detect contaminants (for quality and purity, etc.) during production as well as post production.

The LabSpec line of instruments, through its many and varied application uses, offer a value add to manufacturing and lab testing efforts; use of the LabSpec instrument can help cut down costs while increasing yields by creating no waste, no sample destruction and by its ability to measure multiple constituents at the same time.

Albedo Spatial Variability and Causes on the Western Greenland Ice Sheet Percolation Zone - Goetz Program Report

The stability of the Greenland Ice Sheet (GrIS) in a warming world is a critical research area with societally important implications for future sea level rise, with projected GrIS sea level contributions of at least 20 cm by 21001,2. Previous studies conclude that GrIS mass loss has been accelerating over the past decade, but spatial and temporal variations in GrIS mass balance remain poorly understood due to a complex relationship among precipitation and temperature changes, surface melt, runoff, ice discharge3, and surface albedo4. Satellite measurements indicate that albedo, the proportion of incoming solar radiation that is reflected by the glacier surface, has been declining over the past decade5,6, but the cause of the GrIS albedo change remains poorly constrained by field data. As fresh snow (albedo > 0.85)7 warms and melts, its albedo decreases due to snow grain growth, promoting solar absorption, higher snowpack temperatures and further melt8. However, dark impurities like soot and dust can also significantly reduce snow albedo, even in the dry snow zone2.

Alexander Goetz Instrument Support Program Seeks Research Proposals

Moisture and Protein Composition Characteristics in Barley

May 11, 2017

Near-infrared (NIR) spectroscopy is and has been a trusted analytical method in agronomy for years. Many grain quality indicators are routinely measured or researched using NIR. NIR is a highly cost effective testing process, offering an alternative to ongoing expensive, and time consuming, laboratory-based wet chemistry. ASD’s portable and online NIR technology systems can be implemented at numerous points throughout the grain or seed production process where and when analysis is most beneficial.
