    Notes from the Field – Week 3

    Grant Wiseman Agriculture and Agri-Food Canada Week 3 provided 7 days of much needed sunshine allowing for a study-site-wide dry down of soils and a significant increase in crop growth. Field crews were able to collect vegetation samples twice and soil moisture measurements four times! For more information, visit the SMAP Notes from the Field […]

    Odds & Ends: Batu Tara Volcano Emits a Wispy Plume

    Active since 2006, Batu Tara continues to puff away. A thin volcanic plume streams northwest from the cloud-shrouded volcano. The Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite collected this natural-color image on June 21, 2012. NASA image By Jesse Allen and Robert Simmon using EO-1 ALI data.

    Discovering Local Treasures

    Tom Jackson USDA ARS Hydrology and Remote Sensing Laboratory Having been involved in many field campaigns, one of the things that is interesting to do while driving around to the various test sites is to look for “roadside attractions”. There are a number of websites for tracking these down. On Saturday my route, which covered […]

    Silent Spring Turns 50

    On June 16, 1962, The New Yorker began publishing a serialized version of Silent Spring by Rachel Carson. Spring would eventually turn silent, Carson warned, because widespread pesticide use was killing so many birds that there might be none left to sing. The book provoked a strong reaction from the pesticide industry, but also led to […]

    Crop Structure Sampling

      During the SMAPVEX12 campaign measurements are being made simultaneously by airborne remote sensing instruments (PALS and UAVSAR) and by in situ sampling of the field sites. Measurements of the vegetation/crop structure characteristics and attributes during the vegetation growth phases are an important part of the data collection. Crop structure measurements collected during the campaign […]

    Forest Sampling

      Aspen trees (deciduous forest) comprise more than 90% of the sampled SMAPVEX12 forest sites, with an understory layer of shrubs and grass. The dense shrubs make it difficult to access the sites, therefore the soil moisture and vegetation sampling schemes adopted for these sites are different from the cropland sites. A representative circular area […]
