Those of us lucky enough to be sitting by a window can predict the conditions just by appear outside , but for the less privileged , weather prognostication and psychoanalysis is getting estimable and better . Tomorrow.io justreleased the resultsfrom its first two radar satellites , which , thanks to machine learning , turn out to be private-enterprise with tumid , more one-time - school forecasting tech on Earth and in field .
The company has beenplanning this mission since it was call ClimaCell , back in 2021 , and the results being released today ( and formally present at a weather forecasting conference soon ) show that their gamey - technical school approach works .
weather condition forecasting is complex for a lot of understanding , but the interplay between richly - powered but legacy hardware ( like radar networks and old satellites ) and innovative software is a big one . That infrastructure is powerful and valuable , but to improve their output requires a batch of work on the figuring side — and at some point you start get diminishing returns .
This is n’t just “ is it going to rain down this afternoon ” but more complex and significant predictions like which centering a tropic storm will move , or precisely how much rainfall fell on a given neighborhood over a storm or drought . Such insights are increasingly important as the climate changes .

Space is , of course , the obvious position to endow , but weather infrastructure is prohibitively big and backbreaking . NASA ’s Global Precipitation Measurementsatellite , the gold standard for this theatre of operations launch in 2014 , uses both Ka ( 26 - 40 GHz ) and Ku ( 12 - 18 GHz ) band radiolocation , and weigh some 3,850 kilograms .

Tomorrow.io ’s plan is to create a new place - base radar infrastructure with a modern twist . Its satellites are pocket-sized ( only 85 kilo ) and utilize the Ka - band only . The two satellites , Tomorrow R1 and R2 , launched in April and June of last year , are just now , after a foresighted period of shake - out and testing , beginning to show their quality .
In a series of experiments that the companionship is be after to release in a daybook later this year , Tomorrow claims that with only one radar band and a fraction of the mass , their satellites can produce results on equivalence with NASA ’s GPM andground - based systems . Across a variety of task , the R1 and R2 satellite were able to make likewise accurate or even good and more accurate predictions and notice as GPM , and their results also add intimately with the ground radio detection and ranging data .
They accomplish this though the use of a political machine encyclopaedism model that , as Chief Weather Officer Arun Chawla delineate it , roleplay as two official document in one . It was trained on datum from both of the GPM ’s radio detection and ranging , but by learning the human relationship between the observation and the difference between the two microwave radar sign , it can make a similar prediction using just one band . As their web log post arrange it :
The algorithm is trained with these two-fold - relative frequency - derive precipitation profiles but only uses the Ka - band observations as stimulation . Nevertheless , the complex family relationship between the reflexion profile shape and hastiness is “ learned ” by the algorithm , and the full hurriedness profile is retrieved even in cases where the Ka - dance orchestra reflectivity is completely attenuated by heavy precipitation .
It ’s a magnanimous succeeder for Tomorrow.io if these results tear apart out and generalise to other weather condition patterns . But the idea is n’t to interchange the U.S. infrastructure — GPM and the ground radiolocation connection are here for the prospicient haul and are priceless assets . The real trouble is that they ca n’t be duplicated easily to get over the rest of the world .
The company ’s hope is to have a web of satellite that can cater this level of elaborate prediction and psychoanalysis globally . Their eight planned product satellites will be bigger — around 300 kilogram — and more open .
“ We are act on providing tangible - time precipitation data anywhere in the world , which we conceive is a game changer in the athletic field of weather condition foretelling , ” Chawla said . “ In that regard we are working on truth , global accessibility and latency ( measure out as the time between the signal being catch by the satellite and the datum being available for ingesting into products ) . ”
They ’re also making the inevitable data point play , with a more detailed lot of orbital radar imagery to train their own and other organisation on . For that to work , they ’ll need wad more datum , though — and they contrive to blame up the step collecting it with more satellite launching this twelvemonth .
