Congratulations to Alexandre Mathieu for being the first person to correctly identify our Satellite Puzzler from last week. We posted a full caption that explains the image in our Natural Hazards section yesterday, and it appeared at the top of our site as the Image of the Day on June 21st. The image above is a […]
Grant Wiseman Agriculture and Agri-Food Canada Field teams had another successful week despite the weather still not living up to Manitoba’s famous warm sunny summers. The question on everybody’s mind is not if it is going to rain tomorrow but when? Week 2 contained two full soil sample day efforts, four vegetation collection days, the […]
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 […]
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 […]
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 […]
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 […]
Andreas Colliander Jet Propulsion Laboratory On the second science data acquisition flight of PALS (on June 12) I got to fly on board the Twin Otter aircraft for the flight segment after the mid-day refueling stop at Winnipeg airport. Due to the minimal requirement for a second PALS operator on this flight I took Ian’s […]
Eni Njoku Jet Propulsion Laboratory Mariko Burgin University of Michigan Today the skies are clear. PALS is flying again today, and also flew on June 12th. So this is the third PALS flight day. There is hardly a cloud in sight anywhere as PALS takes off. The soil moisture sampling crews are out. […]
Grant Wiseman Agriculture and Agri-Food Canada After much preparation and anticipation it is hard to believe the first week of the SMAPVEX12 campaign is already behind us. The week began with a successful training session held at the Regional Operation Centre (ROC) in Winnipeg. Field teams were instructed on how to use Hydra Probes, CropScan […]
