Scatter Plot是一个方便的工具,可以最大限度地提高大气科学中数据可视化的效率。 虽然有许多现有的通用数据可视化软件获得了广泛应用,但不能满足许多大气科学特定的研究目的,这促使了Scatter Plot 程序的开发。 本程序包括WODR, Deming和York算法进行线性回归,这三种算法考虑了X和Y都包含不确定性(观测误差),对大气的应用而言更加客观地反映真实情况。它是基于Igor的,并且包含大量用于数据分析和图形绘图的有用功能,包括批量绘图,通过图形界面实现数据掩蔽,Z轴的颜色编码,根据数据或字符串进行过滤和分组。

Scatter Plot is a handy tool to maximize the efficiency of data visualization in atmospheric science. Many existing generalized data visualization software had been extensively used, but they remain unable to fulfill a number of specify research purposes in atmospheric science. That becomes the motivation of Scatter Plot development. The program includes Deming and York algorithm for linear regression, which considers uncertainties in both X and Y, and is more realistic for atmospheric applications. Scatter Plot is Igor based, and packed with a variety of useful features for data analysis and graph plotting, including batch plotting, data masking via GUI, color coding in Z-axis, data filtering and grouping on different time scales (year, season, month, hour, day of week, etc).

HistBox is an Igor Pro based toolkit that maximize the efficiency of data visualization in atmospheric science. Numerous existing generalized data visualization software had been widely used by the community, but a number of features are lacked to satisfy many specified research purposes in atmospheric science. That leads to the development of HistBox, which enables batch plotting for histogram and box plot with specific optimization for atmospheric science (e.g. batch plotting by year/season/month, by hour, by day of week, by user defined string). The toolkit also provides data averaging and alignment function which are common steps in atmospheric data processing. Batch plotting and comprehensive data sorting, grouping and screening features ensure efficient data visualization.

由Millet (2005, JGR)最初提出的最小相关系数法(MRS)是确定性示踪法中的一次比值的有效方法。本程序的目的是通过一个用户友好的图形界面来执行MRS计算。MRS的应用不仅限于OC/ EC示踪法计算SOC,只要一个可靠示踪物,就可扩展到其他的应用中(例如计算黑碳吸光增强系数Eabs)。
本程序的MRS计算可以通过不同的时间维度(批处理计算)来完成:年,年/季,季,年/月,月,按年及月和小时。数据筛选功能也被提供了用以抓取特定的数据子集进行MRS计算。

Minimum R Squared Method (MRS) initially proposed by Millet et al. (2005) is a useful method to determine the primary ratio in the tracer method. This Igor Pro based toolkit facilitates MRS calculation via a user-friendly GUI. The MRS application is not limited in the OC/EC tracer method, but can also be extended to other applications (e.g. BC light absorption enhancement, Eabs) as long as a reliable tracer is available.
MRS calculation can be done by different temporal cycles (batch calculation): by year, by year&season, by season, by year&month, by month, by year&month&hour. A data filter is also available to calculate MRS on a specific subset of data using a number of user-defined constraints.

从基于膜采样的测量获得的吸收系数数据(例如Aethalomenter AE31/AE30)需要仔细校正,因为其固有的系统误差,包含采样膜的matrix效应,散射效应和载荷效应。bATN(采样膜上的光衰减)和 babs(环境空气中悬浮的气溶胶的光吸收系数)之间的非线性关系已成为Aethalomenter的挑战,因为在其输出数据中默认地假设为线性关系。 本工具包提供一个用户友好的界面来执行Weingartner(2003)和Virkkula(2007)算法数据订正。 此外本工具包还提供QA / QC特性,包括传感器电压的等统计信息。
本工具包供学术界/非商业目的免费使用。

Data acquired from filter-based measurements such as Aethalomenter (AE31/AE30) needs carefully correction due to its inherent systemic error, i.e., filter matrix effect, scattering effect and loading effect. The non-linear relationship between bATN (light attenuation on the filter) and babs (light absorption coefficient of suspended aerosol in ambient air) has become a challenge for Aethalomenter, as a linear relationship is assumed by default in its output data. This toolkit provides a user-friendly interface to implement Weingartner (2003) and Virkkula (2007) algorithm for Aethalometer data correction. QA/QC features are also provided, including statistics of sensor voltage.
This Igor Pro based toolkit can be used freely for academic/noncommercial purposes.
