Crowdsourcing4Climate: Community Rainfall Collections Pilot Study (Birmingham, Manchester, Leicester) 1 Crowdsourcing4Climate: Teacher Guide What are we doing and why? ‘Crowdsourcing’ means obtaining information from the community, via the internet, social media, sensors and other offline methods, and is becoming an increasingly popular method to collect data, both manually and automatically for a range of purposes. This pilot study is based on the CoCoRaHS (http://www.cocorahs.org/) project in US, which collects public supplied data (from rain gauges and observations) on a daily and perevent basis. The data is then used in a variety of scientific research, such as: adjusting and validating radar and satellite measurements; weather forecasting; and decisionmaking for extreme events such as flooding, as well as providing a great improvement in spatial data coverage. It is also great to get kids involved in some real citizen science! We need proof that this project can work in the UK, so are conducting a pilot study in several schools across three major cities (Birmingham, Manchester and Leicester) during JuneJuly 2013 using homemade rain gauges to collect daily rainfall amounts. This data will then be compared to standard Met Office rainfall data to check quality. Simple Directions 1) Build a simple and inexpensive rain gauge, using the directions provided here. 2) Position the rain gauge in school playground/field – at ground level and away from buildings, using sand or bricks to secure the gauge so that it won’t be blown over. 3) Every weekday at 9am (+/ 1 hour) record the depth (in millimetres) of the water (using record sheet overleaf – note any issues/problems) [NOTE: Monday’s measurement will cover the weekend data] 4) Send the daily amounts via email ([email protected]) 5) At the beginning of the week we will then send you a map showing your data, as well as the data collected by the other schools in your area, and from the other cities around the UK.

Crowdsourcing4Climate:  Teacher  Guide    

What  are  we  doing  and  why?  

 

‘Crowdsourcing’  means  obtaining   information   from   the   community,   via   the   internet,   social  media,  

sensors  and  other  offline  methods,  and  is  becoming  an  increasingly  popular  method  to  collect  data,  

both  manually  and  automatically  for  a  range  of  purposes.    This  pilot  study  is  based  on  the  CoCoRaHS  

(http://www.cocorahs.org/)  project  in  US,  which  collects  public  supplied  data  (from  rain  gauges  and  

observations)  on  a  daily  and  per-­‐event  basis.  The  data  is  then  used  in  a  variety  of  scientific  research,  

such   as:   adjusting   and   validating   radar   and   satellite   measurements;   weather   forecasting;   and  

decision-­‐making   for  extreme  events   such  as   flooding,  as  well   as  providing  a  great   improvement   in  

spatial  data  coverage.    It  is  also  great  to  get  kids  involved  in  some  real  citizen  science!  We  need  proof  

that  this  project  can  work  in  the  UK,  so  are  conducting  a  pilot  study  in  several  schools  across  three  

major   cities   (Birmingham,  Manchester   and   Leicester)   during   June-­‐July   2013   using   homemade   rain  

gauges   to   collect   daily   rainfall   amounts.   This   data  will   then   be   compared   to   standard  Met   Office  

rainfall  data  to  check  quality.  

 

Simple  Directions  

 

1) Build  a  simple  and  inexpensive  rain  gauge,  using  the  directions  provided  here.  

2) Position   the   rain   gauge   in   school   playground/field   –   at   ground   level   and   away   from  

buildings,  using  sand  or  bricks  to  secure  the  gauge  so  that  it  won’t  be  blown  over.  

3) Every  weekday  at  9am  (+/-­‐  1  hour)  record  the  depth  (in  millimetres)  of  the  water  (using  

record  sheet  overleaf  –  note  any   issues/problems)   [NOTE:  Monday’s  measurement  will  

cover  the  weekend  data]  

4) Send  the  daily  amounts  via  email  ([email protected])      

5) At  the  beginning  of  the  week  we  will  then  send  you  a  map  showing  your  data,  as  well  as  

the  data  collected  by  the  other  schools   in  your  area,  and  from  the  other  cities  around  

the  UK.

How  to  make  your  own  rain  gauge      

 

                   

Method      1) Cut  off  the  top  of  the  bottle  at  about  a  quarter  of  the  way  down  (as  shown  in  the  above  

diagram)  where  the  diameter  is  constant.  Cut  smoothly.      

2) Take  the  bottle  top  that  you  have  cut  off,  turn   it  upside  down  and  place   it  back   in  the  

bottom  part  of  the  bottle.   It  should  fit  snugly  but  to  make  sure  it  does  not  fall  out  use  

tape  to  hold  the  two  halves  together.  Put  a  hole  in  the  bottle  somewhere  near  the  top,  

so  that  you  can  empty  it  after  taking  the  measurements  every  day!  

3) MAKE  A  NOTE  OF  THE  DIAMETER  OF  THE  BOTTLE  –  we  will  use  this  to  calculate  rainfall  

amounts,  so  that  they  can  be  compared  with  standard  rainfall  measurements.    

4) The   bottles   are   usually   shaped   at   the   bottom;   however,   you   need   a   completely   flat  

bottom   to   be   able   to   measure   the   depth   accurately.   To   achieve   this   pour   in   some  

brightly  coloured  jelly  mixture  and  let  it  set  in  the  bottom  of  the  bottle.  Depths  can  then  

be  measured  from  the  top  of  the  jelly.      

5) Attach  a  ruler  to  the  side  of  your  rain  gauge  in  order  to  measure  the  amount  of  water  

collected,  or  mark  the  scale  (in  millimetres)  on  the  bottle.  Remember  to  line  up  the  zero  

with  the  top  of  the  jelly  not  the  bottom  of  the  bottle.    

6) Secure  the  rain  gauge  outside  in  a  suitable  location,  using  a  bucket  of  sand,  or  bricks,  to  

keep  it  upright.    

Jelly  to  here  

Use  tape  to  secure    

Equipment      • A  standard,  straight-­‐sided  2  litre,  

clear  plastic  drinks  bottle  • Scissors  • Tape  (e.g.  duct  tape,  brown  tape)  • Jelly  (3  or  4  cubes  made  up  as  

directed  on  the  packet)    • Ruler  • Marker  pen  • Sand  or  bricks  

 

Make  a  hole  near  the  top  of  outer  bottle  for  tipping  rainwater  away
