Day 2 of our Fundamentals of Build-It-Yourself Environmental sensors course (https://t.co/dAgCC0sJzr) in Leigh-on-Sea - @markmulligan presenting https://t.co/TqdMNKNWJ7's sensor design and live network #catchment2coast

[Reagan Pearce @Reagan_EnviSci]

Excited to share a new paper: design, construction, and testing of an #Arduino-based, in situ water depth sensor, following a low-cost, #opensource approach. A collaborative effort between @drMChad @drkrischan @carlsayerUCL, Bruce Main, and Ian Patmore https://t.co/Yk3MgcQWs4

@geographynicole HUGE congratulations Nicole!!🎓🌟We'd love for you to come back and talk about your research at some point down the line. Celebrate properly in the interim! 🍾🥂🥳

[Dr Kris Chan @drkrischan]

@aline_marine Any problems please let me know (feedback very welcome too!)

I'll be 🎥 a walkthrough at some point soon

🎉Just released my very first #RStats package!🎁

prepCLMdata helps format climate data for #DIVAGIS. It's easiest than ever to perform past, present & future species niche modelling with ECOCROP using the package🌡️🌧️

Thames Estuary fieldtrip to Leigh-on-Sea as part of the @NERCscience Low Cost Sensor training course from @kclgeography. Learning how to use a range of #freestation sensors

London has had a pretty dry year, and river flows have been notably low according to @EnvAgencySE.

Quite surprising that a little bit of rain yesterday, probably about 15mm, caused this much sewage dumped straight into waterways.

How is this legal?

[Dr Kris Chan @drkrischan]

Environmental researchers - want to learn how to build your own env loggers?

KCL Geography is running 3-day courses on Fundamentals of Build-It-Yourself Environmental Sensors in Apr/May.

Free & open to all. Priority given to PhDs/ECRs and NERC funding.

Just discovered the OSM Buildings project (the open-source version) which creates a beautiful interactive cityscape.

We (@dawson_t @drkrischan @drarnoutvans & others) are using #FreeStation #WaterWorld #CostingNature to examine impacts of #ClimateChange and #LandUseChange on the #Paramos of #Colombia as presented by @UKRI_News this week at #COP26 @PorElParamo Supported by @NewtonFund

[Dr Kris Chan @drkrischan]

Great day out on Hampstead Heath with our new @kclgeography undergraduates - great to meet so many of you! Here's a quick overview of the pond station and some of the stuff we covered.

Out again on Masters' field courses tomorrow!

[Dr Kris Chan @drkrischan]

@hev_needham9 Incredible news Heather! Well done on finishing the degree too! 😀🎉

[Dr Kris Chan @drkrischan]

Can't help but 😆 prepping the #clustering lecture at the names they gave some methods: CLARA (Clustering Large Applications), PAM (Partitioning Around Medoid), DIANA (Divisive Analysis), FANNY (Fuzzy Analysis), AGNES (Agglomerative Nesting), MONA (Monothetic Analysis). #ml

[Dr Kris Chan @drkrischan]

Brilliant simultaneous in-person & virtual #JBTlab session for the @kclgeography @London_NERC_DTP week

All the 🤔, hard work, planning and experience results a seriously polished practical. Lucky to be working with such a talented team!

#Landsat crosses the equator 10-10:25am meaning the sun is generally eastward

[Dr Kris Chan @drkrischan]

DYK: #Landsat surface reflectance data=✅terrain corrected but❌topographically corrected?

Terrain: pixels appears WHERE they should
Topographic: pixels corrected for sun angle (see GIF)

A particular problem in #mountainous areas. Useful to correct before land classification
