Comparing the performance of different satellite sensors in global land cover change (LCC) monitoring is necessary to assess their potential and limitations for more accurate and operational LCC estimations. This paper aims to examine and compare the performance in LCC monitoring using three satellite sensors: PROBA-V, Landsat 8 OLI, and Sentinel-2...

Annual global land cover maps (GLC) are being provided by several operational monitoring efforts. However, map validation is lagging, in the sense that the annual land cover maps are often not validated. Concurrently, users such as the climate and land management community require information on the temporal consistency of multi-date GLC maps and s...

BFAST Lite is a newly proposed unsupervised time series change detection algorithm that is derived from the original BFAST (Breaks for Additive Season and Trend) algorithm, focusing on improvements to speed and flexibility. The goal of the BFAST Lite algorithm is to aid the upscaling of BFAST for global land cover change detection. In this paper, w...
Article
Currently most global land cover maps are produced with discrete classes, which express the dominant land cover class in each pixel, or a combination of several classes at a predetermined ratio. In contrast, land cover fraction mapping enables expressing the proportion of each pure class in each pixel, which increases precision and reduces legend c...

Construction of transportation infrastructure is a vital step in boosting economic and societal opportunities and often results in land use changes. In this study, we focus on the land use dynamics of the urban agglomeration around Hangzhou Bay, where the Qiantang River flows into the East China Sea. The Hangzhou Bay Bridge crosses the bay since 20...

Unmanned Aerial Vehicle (UAV)-based measurements allow studying sun-induced chlorophyll fluorescence (SIF) at the field scale and can potentially upscale results from ground to airborne/satellite level. The objective of this paper is to present the FluorSpec system providing SIF measurements at the field level onboard a UAV, and to evaluate the pot...
Conference Paper
Full-text available
The actual photosynthesis is important for studying crop dynamics. Remote sensing of vegetation has the potential to greatly improve our understanding in this respect. Recently, sun-induced chlorophyll fluorescence (SIF) was proven to be an indicator for the functional status of instantaneous plant photosynthesis. However, the relationships between...

PurposeRecent works have shown that fertilization has an important influence on soil respiration (Rs); however, the underlying mechanisms involved in regulating Rs in greenhouse vegetable production (GVP) systems remain unclear.Materials and methodsSamples from six kinds of soils that were amended with different fertilization patterns (8 years) wer...

Soil aggregation, microbial community, and functions (i.e., extracellular enzyme activities; EEAs) are critical factors affecting soil C dynamics and nutrient cycling. We assessed soil aggregate distribution, stability, nutrients, and microbial characteristics within >2, 0.25-2, 0.053-0.25, and <0.053 mm aggregates, based on an eight-year field exp...
Article

Soil microbial communities and enzyme activities together affect various ecosystem functions of soils. Fertilization, an important agricultural management practice, is known to modify soil microbial characteristics; however, inconsistent results have been reported. The aim of this research was to make a comparative study of the effects of different...

The current standard of land cover classification is to assign each pixel to one land cover class, which at coarse resolution causes loss of information about mixed land cover. Fuzzy land cover classification, which assigns fractions of each land cover class to each pixel, can deal with mixed pixels. However, so far its application has been limited...
Thesis
Full-text available
Logging in the Amazon is primarily selective, with individual commercial trees cut down, leaving the others untouched. The direct effects of selective logging are difficult to quantify using remote sensing techniques due to the small extent of treefall gaps left after logging, and the quick canopy regrowth that follows. In this thesis, the time ser...
Thesis
Full-text available
Global land cover (GLC) classification is well established, and GLC products are used as input to a variety of scientific models. However, traditional GLC classification assumes that each pixel in a map can be classified into one of the predefined land cover classes. This is rarely the case in reality due to heterogeneity in land cover that results...
