生态水文课题组 《ACS earth and space chemistry》吞吐型湖泊 水—气界面碳交换
2023/1/11
湖泊代谢(metabolism)指湖泊生物不断进行的光合和呼吸作用，可通过湖泊总初级生产力（GPP）和湖泊总呼吸（RE）量化。水体二氧化碳分压（pCO2)指溶解在水中的二氧化碳（CO2）分子产生的压力，可用来量化量溶解在水中的二氧化碳的量。pCO2与其他参数，如 pH 值、溶解性无机碳和碱度一样，都用来描述水体的无机碳系统（CO2 (aq)、HCO3-、CO32-）的浓度和形态。湖泊pCO2不仅受...

In this study, we report results from scaling analysis of 2.5 m spatial and 1 s temporal resolution lidar-rainfall data. The high resolution spatial and temporal data from the same observing system al...
Soil Infrastructure, Interfaces & Translocation Processes in Inner Space ("Soil-it-is"): towards a road map for the constraints and crossroads of soil architecture and biophysical processes
Soil Infrastructure Interfaces Translocation Processes Inner Space
2009/9/11
Soil functions and their impact on health, economy, and the environment are evident at the macro scale but determined at the micro scale, based on interactions between soil micro-architecture and the...
Improved estimation of flood parameters by combining space based SAR data with very high resolution digital elevation data
synthetic aperture radar devastating catastrophes flood parameters
2009/7/22
Severe flood events turned out to be the most devastating catastrophes for Europe's population, economy and environment during the past decades. The total loss caused by the August 2002 flood is estim...
Orographic effects on convective precipitation and space-time rainfall variability：preliminary results
convective precipitation rainfall
2009/5/18
In the EFFS Project, an attempt has been made to develop a general framework to study the predictability of severe convective rainfall events in the presence of orography. Convective activity is embed...
Using a spatio-temporal dynamic state-space model with the EM algorithm to patch gaps in daily riverflow series
patch gaps daily riverflow series
2009/5/18
A spatio-temporal linear dynamic model has been developed for patching short gaps in daily river runoff series. The model was cast in a state-space form in which the state variable was estimated using...
Empirical Mode Decomposition in 2-D space and time：a tool for space-time rainfall analysis and nowcasting
2-D space Empirical Mode Decomposition space-time rainfall
2009/5/18
A data-driven method for extracting temporally persistent information, at different spatial scales, from rainfall data (as measured by radar/satellite) is described, which extends the Empirical Mode D...
Catchments as space-time filters – a joint spatio-temporal geostatistical analysis of runoff and precipitation
space-time filters runoff precipitation
2009/5/15
In this paper catchments are conceptualised as linear space-time filters. Catchment area A is interpreted as the spatial support and the catchment response time T is interpreted as the temporal suppor...
