title: JapanFlux2024 RU-NeC Neleger Cutover

description: In order to obtain basic information for GHG reduction by permafrost disturbance control, it is necessary to monitor changes in the GHG budget at the disturbance site and to quantitatively evaluate the impact.
Since permafrost disturbance is induced by thermal equilibrium collapse due to disturbance of the overlying ecosystem, changes in the surface heat and water balance due to ecosystem disturbance should also be monitored simultaneously.
The purpose of this study was to determine the effects of forest disturbance on the surface heat, water, and CO2 budgets and permafrost dynamics in a permafrost area through long-term monitoring.
Long-term continuous monitoring of surface heat, water, and CO2 budgets was conducted in larch forests, fire sites, and logging sites near Yakutsk, Russian Federation.

title: JapanFlux2024 JP-Spp Sapporo forest meteorology research site

description: Sapporo forest meteorology research site is located in a hilly area neighboring urban district of Sapporo city. It is a secondary boreal deciduous broadleaf forest which had grown after wildfire. Century-old japanese white birch is its dominant species but it is on the wane and oak trees are gradually taking over the forest. The climate of this area is classified in cool-temperate, with relatively hot and dry summer and heavily snowing winter. We are observing the CO2 and energy budget in a typical secondary forest of northern Japan under various climatic conditions.
The forest around the observation tower was badly damaged by typhoon in September 2004. Most of the fallen trees are untouched to study the natural transition of ecosystem. The observation tower had restarted its operation in June 2005, after the recovery from damage.
The site is supporting the continuous research activities on ecology, physiology, pedology and hydrology and accumulating the results for the future studies which especially focus on transition of forest ecosystem.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.

title: JapanFlux2024 CN-In8 Inner Mongolia medium grazing

description: We designed the field experiments to study the effects of the grazing strength on the degradation of grassland and to know the grazing capacity at the grassland in semi-arid area in Inner Mongolia.The experiments started in1991 autumn and continued to autumn in1995.
An experimental grazing section (260m X 200m in rectangular area) was established on the grassland (1.6km north-east from the Naiman Station),where the micro meteorological observation had been conducted in1991,as the site of typical grassland.
The experimental site was divided by barbwire fence to three 75m X 200m rectangular areas and one 35m X 200m area.
The longer side of the four rectangles was directed to north-south to obtain the maximum fetch for the prevailing wind direction (south) during the observation period.
Each of the four areas was treated by different grazing densities (different sheep numbers in each area) from May1992.
The grazing strength of the three 75m X 200m areas was set as 6, 4 and 2 sheep/ha,namely "Heavy grazing site", "Medium grazing site" and "Light grazing site", respectively.
In the Medium grazing site,four sheep per hectare were grazed during the grazing period.
Grass condition was a little bit poorer than that of natural grassland with traditional grazing.
The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the Heat balance Bowen ratio method and the Gradient method.

title: JapanFlux2024 CN-In3 Inner Mongolia soybean

description: Soybean (Glycine max) was cultivated at no-irrigated fields around Naiman region.However,the Naiman Station has an experimental field with an irrigation system for the study to clarify the efficacy of irrigation. The micrometeorological measurements were conducted at soybean fields of the irrigated field ( belongs to the Station) and at no-irrigated fields ( belongs to village farmers).The irrigation interval of the measurement site was decided by the Naiman Station.
The measurement was carried out in early August 1991,late August 1992 and mid-August 1993. In1991, the study site was located at an extensive flat field near the Naiman Station.This field was irrigated almost every two weeks.
The area of the soybean field was about 0.4ha (50m from north to south and about 80m from east to west).In the measurement period,the soybean was in its flowering stage and the canopy height was about 0.5m. In 1992,the study site was located at 1.1km south from the residence of Yaoledianzi village and there was no irrigation system.The area of the study site was about 0.4ha ( about 70 m in diameter ). The canopy height was about 0.7m during the measurement period. 
In1993, the measurement was carried out at both sites of irrigated and non-irrigated fields.The irrigated field was located besides the Naiman Station and the area was about 0.5ha.The canopy height was approximately 0.7m.The no irrigation field was Iocated at 1.5km northeast from the Naiman Station.The field area was about l ha ( 40m from north to south and 250m from east to wes).
The canopy height was approximately 0.3m.
The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the Heat balance Bowen ratio method and the Gradient method.

title: JapanFlux2024 JP-Tef CC-LaG Teshio Experimental Forest

description: The study site lies on a flat terrace inside the Teshio Experimental Forest of Hokkaido University. Its soil, mainly a Gleyic Cambisol, has a surface organic horizon that is about 10 cm thick. Prior to clear-cutting, the dominant tree species were Quercus crispula, Betula ermanii, Abies sachalinensis, and Betula platyphylla var. japonica. Maximum and mean tree heights were 24 and 20 m, respectively. The forest floor was covered with dense evergreen dwarf bamboos (Sasa senanensis and Sasa kurilensis). The plant area index (PAI) values for the canopy trees and the Sasa bamboos, measured using an LAI-2000 leaf-area meter (Li-Cor, Lincoln, NE, USA), were 3.2 and 4.1, respectively, at this parameter's seasonal maximum in 2002. From January to March 2003, trees covering an area of 13.7 ha were clear-cut. The total biomass volume of trees at the site was 2193 m3 (Koike et al. 2001), of which 1203 m3 (~19 t C ha-1) were removed as logs by clear-cutting. Sasa was left intact under the snowpack, but 7 months later, just before the planting of hybrid larch seedlings (in late October 2003), they were strip-cut into alternating 4-m-wide cut and uncut rows in the clear-cut area to give space for the planting of ca 30 000 2-yr-old hybrid larch (Larix gmelinii x L. kaempferi) at a density of 2500 ha-1 (0.04 t C ha-1). In the rows where Sasa remained, Sasa PAI increased steeply from 1 yr after clear-cutting until 2007, reaching a peak at 8.0 in 2010, which is about double the value in 2002 before clear-cutting. In the rows where Sasa was strip-cut, Sasa weeding in the strip cut rows was conducted from once (2005 and 2006) to three times (2004) per year between late May and late July until 2006. Weeding eliminated all Sasa growing between the larch trees. The Sasa was no longer weeded starting in 2007 because the larch were higher than the surrounding Sasa, and were able to receive enough solar radiation to grow without interference. Sasa soon recovered in the strip-cut rows, and in 2008, 2 yr after the last weeding, the PAI was almost the same as that in the surrounding uncut rows, blanketing all gaps between the trees. On the other hand, the PAI of the larch remained low (1.7 in 2010) at its seasonal maximum and was minor compared with that of Sasa. A closed-path eddy covariance system was established in August 2001 on a 32-m-tall tower in the mixed forest to evaluate the CO2 fluxes. A sonic anemometer (DA600-3TV; Kaijo, Tokyo, Japan) and an infrared gas analyzer (IRGA; LI-7000; Li-Cor) were used to evaluate the fluxes. In addition to the existing equipment installed at a height of 32 m, another closed-path system comprising the same instruments was installed at a height of 4.6 m in October 2003 after clear-cutting, and the measurements were on going, although the height and instruments were changed several times.

title: JapanFlux2024 RU-SkP Yakutsk Spasskaya Pad larch

description: Located in the center of the Lena River system, which stretches east to west from near Lake Baikal to the Sea of Okhotsk, it is conveniently situated as a base for trans-Siberian and Arctic Ocean expeditions along the Lena River.
Its winter temperature is the lowest among the world's cities. 
On the other hand, in summer, despite its latitude, the temperature is relatively high, making it a typical continental climate with extremely large differences in temperature (in summer, the morning and evening temperatures are considerably cooler than the daytime heat, so the daily range is also large). It is also the largest city built on permafrost in the world, and many buildings are built on concrete piles.The turbulent fluxes of sensible heat, latent heat and CO2 were measured using the eddy covariance system.

title: JapanFlux2024 ID-PaD Palangkaraya drained forest

description: The study was conducted in tropical peatlands in the upper catchment of the Sebangau River near Palangkaraya, the capital city of Central Kalimantan province, Indonesia. In Central Kalimantan, a large peatland area was deforested and drained during the late 1990s, mainly to develop farmlands according to a national project: the Mega Rice Project (MRP). The forest had also been selectively logged until the end of the 1990s. Dominant tree species and the microtopography of the forest floor resembled those at the ID-Puf site. A large canal (25 m wide x 3.5 - 4.5 m deep) that was excavated in 1996 and 1997 has functioned effectively to facilitate drainage of the forest. A 50 m high tower was built for flux measurement in 2001. The tower is located about 400 m from the canal. Fetches were about 400, 500, 1500 m, and longer than 5000 m, respectively, for the north, east, west, and south directions.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.
