LBA-ECO CD-10 CO, CO2 and Meteorological Data, Maxaranguape, Brazil
简介
本数据集报告了 2003 年 1 月 4 日至 2006 年 12 月 27 日期间在巴西东北部马克萨兰瓜佩大气观测站测得的一氧化碳 (CO) 和二氧化碳 (CO2) 浓度、风向、风速和气温。数据为 30 分钟平均值。马克萨兰瓜佩观测到的浓度代表了亚马逊河流域上游大气边界条件，可与圣塔伦数据和其他数据集结合使用，估算这些气体的区域预算（Kirchhoff 等人，2003）。此数据集包含一个逗号分隔的 ASCII 文本文件。
摘要
File name: CD10_Maxaranguape_CO_CO2_2003-2006.csv
| Column | Heading | Units/format | Description |
|---|---|---|---|
| 1 | Day_of_year | Decimal day of the year with hour indicated by fraction based on UTC (1.5 = noon on Jan 1st) | |
| 2 | Seq_date_2002 | Decimal day since January 1st 2002 based on UTC (local time is GMT-4) | |
| 3 | Date | yyyy/mm/dd | Sampling date |
| 4 | Hour | Hour is the start of the half hourly sampling period on a 24 hour clock on UTC: (local time is GMT -4) | |
| 5 | Wind_spd | m s-1 | Mean wind speed in meters per second (m s-1) computed as a vector average on 30 min intervals |
| 6 | Wind_dir | degrees | Mean wind direction in degrees computed as a vector average on 30 min intervals |
| 7 | T_air | degrees C | Mean air temperature in degrees Celsius for the 30 min sampling period |
| 8 | Std_dev_T_air | degrees C | Standard deviation of the mean air temperature |
| 9 | CO2_mix_ratio | ppmv | CO2 mixing ratio in micromoles/mole (ppmv) |
| 10 | Std_dev_CO2_ratio | ppmv | Standard deviation of the calculated mean CO2 ratio |
| 11 | Npts_CO2 | Number of one minute averages included in the half-hourly reported CO2 ratio | |
| 12 | CO_mix_ratio | ppbv | Carbon monoxide (CO) mixing ratio reported in nanomoles/mole (ppbv) |
| 13 | Std_dev_CO_ratio | ppbv | Standard deviation of the calculated mean CO ratio |
| 14 | Npts_CO | Number of one minute averages included in the half-hourly reported CO ratio. The maximum number will be less than 30 because of the periodic zeroing | |
| Missing data are represented by -999 | |||
Site boundaries: (All latitude and longitude given in degrees and fractions)
| Site (Region) | Westernmost Longitude | Easternmost Longitude | Northernmost Latitude | Southernmost Latitude | Geodetic Datum |
|---|---|---|---|---|---|
| Rio Grande do Norte - Maxaranguape Atmospheric Observatory (Rio Grande do Norte) | -35.2605 | -35.2605 | -5.496 | -5.496 | South-American Datum, 1969 (SAD-69) |
