​LBA-ECO CD-06 CO2 Exchange in River Systems Across the Amazon Basin: 2004-2007

简介

该数据集提供了 2004 年 7 月 1 日至 2007 年 1 月 23 日期间南美洲亚马逊河流系统 75 个站点的二氧化碳通量率、气体转移速度和二氧化碳分压的测量数据。


2004 年 6 月至 2007 年 1 月期间，在亚马逊河流域开展了多次采样活动，采样流量从低到高不等。采样区域涵盖了整个流域观测到的各种化学特征，例如 pH 值高低以及悬浮沉积物负荷。


该数据集中有一个以逗号分隔的数据文件。

Column Heading Units/format Description
1 Basin Major river basin in which the sampling station is located
2 Location Sampling station location usually given as nearby municipality or local name of the igarape or lake
3 Site_code Unique site identifiers for sites used in this and other studies
4 Date YYYYMMDD Sample collection date
5 Time HH:MM Sampling time in local time reported on a 24 hour clock
6 Env_type Description of the sampling location with special attention to the size of the water body and flow characteristics
7 Comments Comments from field notebooks about sampling location
8 Latitude decimal degrees Geographic coordinates of the sampling location in decimal degrees of latitude. Where location was not measured directly it was approximated from the nearest station with measured coordinates
9 Longitude decimal degrees Geographic coordinates of the sampling location in decimal degrees of longitude. Where location was not measured directly it was approximated from the nearest station with measured coordinates
10 Elev km Elevation of the sampling location reported in kilometers. Where direct measurements were not made, values were approximated from the nearest station with reported values
11 Wind_spd_avg m per s Average windspeed measured at 1.5 m above water independently for 3-5 minutes during the chamber sampling period and reported in meters per second
12 Wind_spd_max m per s Maximum windspeed at 1.5 m above water from independent measurements done for 3-5 minutes during the chamber sampling period and reported in meters per second
13 RH % Relative humidity of the air reported in percent
14 T_air degrees C Air temperature reported in degrees Celsius. Where direct measurements were not made an approximate value was used
15 T_water degrees C Water temperature at surface reported in degrees Celsius. Where direct measurements were not made, an approximate value was used
16 pCO2_water ppm Partial pressure of CO2 in the surface water reported in parts per million
17 pCO2_air ppm Partial pressure of CO2 in the air reported in parts per million
18 Time_start seconds Time at which the measurements used in the determination of the gas transfer velocity began reported in seconds
19 Time_end_1 seconds Time at the end of the first sampling period used in the determination of the gas transfer velocity reported in seconds
20 Time_end_2 seconds Time at the end of the second sampling period used in the determination of the gas transfer velocity reported in seconds
21 Time_end_3 seconds Time at the end of the third sampling period used in the determination of the gas transfer velocity reported in seconds
22 pCO2_init ppm Partial pressure of CO2 in the chamber at the start of the measurement period reported in parts per million
23 pCO2_end_1 ppm Partial pressure of CO2 in the chamber at the end of the first measurement period (60 seconds) reported in parts per million
24 pCO2_end_2 ppm Partial pressure of CO2 in the chamber at the end of the second measurement period (120 seconds) reported in parts per million
25 pCO2_end_3 ppm Partial pressure of CO2 in the chamber at the end of the third measurement period (180 seconds) reported in parts per million
26 Slope_regression ppm per second Slope of the regression between change in CO2 concentration in the chamber (y-axis) and time (x-axis) over the sampling period
27 SE_regression ppm per second Standard error of the slope of the regression
28 Press_atm atm Atmospheric pressure in the chamber reported in atmospheres
29 k_1 cm per hour Gas transfer velocity calculated for the first measured time period (60 seconds)
30 k_2 cm per hour Gas transfer velocity calculated for the second measured time period (120 seconds)
31 k_3 cm per hour Gas transfer velocity calculated for the third measured time period (180 seconds)
32 u_star m per s Friction velocity reported in meters per second and calculated as described in the documentation
33 u_10 m per s Mean windspeed at a height of 10 meters about the water surface reported in meters per second and calculated as described in the documentation
34 FCO2 umol CO2 per m2 per s Air-water CO2 gas exchange flux reported in micromoles CO2 per meter squared per second
missing data are indicated by -9999; missing text data are indicated by na
