Pre lab 8

Image Processing II Introduction In this lab we will be learning various image processing techniques. We will preform pre-processing techniques using Landsat 8 data and apply some image enhancement techniques to improve the contrast and visual interpretability of the images.

The invention of an efficient steam engine by James Watt in meant humans were able to effectively convert fossil fuels into energy, a process that releases carbon dioxide CO2 into the atmosphere. As the industrial revolution gathered pace in the 19th century, the resulting increase in CO2 and other greenhouse gases from land-use change and fossil fuel burning started to warm the Earth.

However, there is no perfect choice. Previously, the period has been used as the historical baseline, but this period includes some large volcanic eruptions and is after greenhouse gas concentrations had already started to rise.

We suggest that the earlier period of is a better choice for this baseline. This is important because we want to assess the changes due to human activity, rather than changes because of other factors.

For example, the early s were cooled by several large volcanic eruptions and so are unsuitable for a baseline. And before there was less solar activity and also several large volcanic eruptions.

Historical changes in different climate forcings. So, by how much have global temperatures changed since pre-industrial? A problem with our chosen pre-industrial period is the limited availability of observed temperature records.

We can make an assessment of changes in global temperature since the period, but the uncertainties are quite large. In our studywe considered the long temperature records that do exist for central England, the Netherlands and Europe, as well as our understanding of historical changes in factors such as greenhouse gases, the sun and volcanic eruptions.

We assessed that global temperatures likely increased by more than 0. Global temperature changes from multiple datasets, presented as the lower bound on warming since the pre-industrial era. Updated from Hawkins et al. What does this mean for the Paris agreement? Now we are able to define the starting line for the global temperature limits stated in the Paris agreement, we can also better define the finishing line.

The new analysis finds that this historical warming assumed by the IPCC is at the lower limit of what we assess is the true change since pre-industrial times. There is also more to learn. We need volunteers to help rescue additional observations of climate from various undigitised sources to better understand the climate of the 19th century.

The suggested period also offers a target to paleoclimate reconstructions to inform this topic. The study also suggests that policymakers might avoid the inevitable uncertainty in defining pre-industrial by reframing the temperature limits in terms of a more modern baseline.

This would allow use of better observations and atmospheric reanalyses to define the starting point, but would require more thought into what X should be.

It would also better inform the difficult decisions about how much greenhouse gas emissions would need to be reduced to avoid breaching agreed global temperature thresholds.

Battery Test Lightbulb Test Procedure 3 - Building a Conductivity Tester and Testing Solutions When you tested the 9V battery and lightbulb, you built a closed circuit, meaning all the wires were connected in a loop.

For this part of the lab you will need to build an open loop device to test several different solutions. 1. View Lab Report - Lab 8 Pre Lab from BIS 2B BIS at University of California, Davis.
